I bought my first mechanical keyboard in 2012 because a LAN party friend swore it would fix my RSI. It did not fix my RSI. It did start an obsession that has cost me a spare bedroom, a soldering iron, and more than 250 logged test sessions since 2021. Every mechanical keyboard comparison I publish has to answer two questions: what does this thing actually do for the person typing on it, and what do you give up to get that?

These four products share a shopping cart and almost nothing else. Two are complete keyboards, one is a set of switches for a board you already own, and one has nothing to do with typing at all. I will be direct about that fourth one when we get to it, because pretending it belongs in a keyboard ranking would waste your time.
The short answer: the WOBKEY Rainy 75 is the pick for most people who want one keyboard that covers wired and wireless, the Logitech G PRO Mechanical TKL is the safer buy if you want a wired board with clicky switches, the Akko V3 Creamy Blue Pro set is the cheapest way to change how an existing hot-swap board feels, and the PetAg KMR belongs in a house with a foster kitten, not on a keyboard shelf.
Logitech G PRO Mechanical TKL Tenkeyless Gaming Keyboard (Clicky) - Black
Tenkeyless layout buys mouse room, clicky switches give loud, unmistakable feedback, wired means nothing to charge or pair
Clicky is unusable on calls and in shared rooms, and the spec line does not advertise hot-swap sockets

How I judged these four, and what I did not do
My normal protocol is 30 days as a daily driver, a decibel meter at 40 cm, a force curve, and a teardown. I did not run all four of these products through that protocol before writing this, and I am not going to pretend otherwise. What follows is a judgment built on published specifications, documented design choices, and two years of logging adjacent gear: boards in the same layout class, switches in the same force range, and the same connectivity options from other brands.
Where a number comes from a spec sheet, I say so. Where a number comes from my bench, I say so. Where I have nothing, I say nothing. That rule is the only reason this site is worth reading, and it applies to a comparison just as much as it applies to a single review.
The Logitech G PRO Mechanical TKL: the known quantity
The product name tells you most of what you need: clicky switches, tenkeyless layout, black. This line was built for players who want a small footprint and an audible, tactile confirmation on every press. Clicky switches do exactly that. The click is the point, and the click is also the problem.
I love clicky switches with my whole heart, and I cannot use them in an open office or on a single work call. A clicky board is the loudest thing on my bench by a wide margin, and the novelty fades long before the noise does. If you share a wall, share a desk, or spend your day on video calls, this is not the board for you. If you work alone and want your fingers to know a key registered, it is.
The TKL layout is the right call for a mouse-heavy setup. Losing the numpad buys you several inches of mouse travel, and if you are not in spreadsheets all day you will not miss it. Tenkeyless is also the layout where aftermarket keycap sets are cheapest and most available, which matters more than people admit three months into the hobby.
The one spec I would confirm before buying is hot-swap. The name and the spec line here advertise clicky switches, not sockets. On a board without hot-swap, the switch decision is permanent, and permanent clicky is a real commitment. My rule has not changed. If a board does not let you pull a switch with a $5 tool, it is obsolete the day you buy it, because you will want to try something else eventually, and a soldering iron turns a 10 minute experiment into a 45 minute session.
The WOBKEY Rainy 75: the one that does everything
The spec line on this board reads like a list of the things I complain about most when they are missing: CNC aluminum case, triple-mode connectivity (wired, 2.4GHz, and Bluetooth), RGB, an FR4 plate, a stainless steel component, a 7000mAh battery, and Cocoa switches in a Pro Black finish. The 75% layout keeps the function row and the arrow cluster while dropping the numpad, which is the layout I would pick for a coding week if someone forced me to choose one.
Two of those specs deserve scrutiny rather than applause.
The first is connectivity. Wireless is real in 2026, but wireless is not the feature. Latency, battery life, and drop-free weeks are the features. A 7000mAh battery is a large number on paper, and how long it lasts depends on backlight brightness and how the radio behaves when your desk sits near a router. I do not have a 30-day driver log for this board, so I will not tell you what its battery does. What I will tell you is that a board with three connection modes is only worth it if all three modes hold, and that is the first thing I would log.
The second is the case and plate combination. A CNC aluminum case changes the weight and the resonance of a board. An FR4 plate flexes where an aluminum plate does not, which softens the bottom-out and shifts the sound toward the deeper end of the spectrum. Those are design decisions, and they show up on day one, unmodded, which my prediction engine weights more heavily than any price tag. A board that sounds good naked was designed. A board that needs a tape mod to sound acceptable was assembled.
The trade-off is real, though: aluminum is heavy, a triple-mode board has more that can fail, and this is the most expensive item on the list. You are paying for the case, the battery, and the layout, not for a logo.
The Akko V3 Creamy Blue Pro: the upgrade for a board you already own
This is not a keyboard. It is 45 switches, listed at 45gf, in a 5-pin housing with a dustproof stem, pre-lubed from the factory. If you already own a hot-swap board and you are bored with what is in it, this is the cheapest way to change how that board feels.
Three things to check before you buy any switch set.
The first is force and feel. The 45gf figure sits in the light-to-medium range where most tactile switches live, and tactile means there is a bump partway down the press that tells your finger the key registered. If your board currently runs clicky switches, a tactile set gets you the feedback without the noise. If your board runs linears and you like them, a tactile set is a real adjustment period, usually about a week.
The second is pin count. Five-pin switches have two plastic locating legs in addition to the metal pins. Boards with 5-pin hot-swap sockets take them as they are. Boards with 3-pin-only sockets require clipping the two plastic legs off with flush cutters, which takes ten minutes. Check which one you own before the switches arrive.
The third is quantity. Forty-five switches fills a small board. It does not fill a 65%, it does not fill a TKL, and it does not come close to a full-size board. If you are buying for anything bigger than a compact layout, count your keys first. This is the most common way people waste money on switches.
On the pre-lubed claim: pre-lubed on a spec sheet is not the same as lubed well. Factory lube varies from consistent to "someone waved a brush in the general direction of the factory." The dustproof stem is a genuine durability feature, and the 5-pin housing is what I want to see in 2026, but I would set expectations at smooth enough rather than hand-tuned.
The outlier: the kitten milk replacer
I am not going to pretend this is a keyboard. PetAg KMR is a ready-to-feed liquid milk replacer for newborn kittens up to a year old, sold as a pack of three 16 oz bottles, with vitamins added and a formula built to be easy to digest. It is on this list because plenty of people who spend $200 on an aluminum case also foster kittens, and when you need this, you need it that day, not in two days.
That is the entire review. If there is a foster kitten in the house, keep some on the shelf. If there is not, skip this row and put the money into switches.
The trade-offs that actually matter
Wired versus triple-mode. The Logitech is a wired board, which means one cable and nothing to charge. The Rainy 75 gives you three connection options and a battery to manage. If you never move your keyboard, wired is simpler and one fewer thing to fail. If you swap between a desktop and a laptop, triple-mode earns its keep.
Clicky versus tactile. The Logitech's clicky switches are louder and more satisfying in an empty room. The Akko set is tactile, which keeps the feedback and drops the click. If you have ever been asked to type more quietly, you already know which side of this you are on.
Complete board versus component. Buying a keyboard is one decision. Buying switches is a compatibility research project: pin count, socket type, plate, and layout all have to line up. The component path is cheaper and gives you more control, but only if you already own a board worth upgrading.
Layout. TKL versus 75%. Both drop the numpad. The 75% keeps the function row and arrows in a tighter footprint. TKL keeps a wider, more standard key arrangement. Neither is better; they are different desks.
The buying answer for each
If I bought the Logitech G PRO Mechanical TKL at retail, would I keep it past day 29? Yes, if I worked alone and wanted a wired board with a click I could feel. No, if I had an open office or a shared living room, because the click is the whole product and I could not use it where I work.
The WOBKEY Rainy 75 is the one I would buy first. The layout, the case material, and the triple-mode connectivity cover the most ground, and the specs that matter are the ones I can verify with a meter and a log rather than a marketing page. If you want a single board to do everything, this is where the money goes.
The Akko set is a yes with a condition: only if you own a hot-swap board with 5-pin sockets and fewer than 45 keys to fill, or you are willing to buy two sets. As a first purchase for someone with no board, it is a dead end.
The PetAg KMR is a yes if there is a kitten in your house and a no otherwise. Some products do not need a ranking.
