So I need to replace my keyboard as it's finally on it's last legs. I'm an extremely heavy rhythm gamer getting 1k+ hrs in just Project Diva a year. The issue is my keyboard is now on it's last legs with multiple keys sticking, not always registering, and I'm also missing my \[ keycap (I lost it somehow while cleaning my keyboard, looked everywhere still can't find it). I needed to replace it and I don't know if I should just stick with what I got now or if there's a different brand/type you all recommend. Currently I use a corsair K100 with Optical Switches due to just how light they are to push down but my biggest issue with it is just how loud the keys are upon pressing and them being picked up my by mic. Other than that I love this keyboard in every game I've played. From Helldivers, Ready or Not, to my extremely fast rhythm games. I know I want a full 100 sized keyboard and I NEED short light keystrokes. I've been looking at some other brands like Wooting and Razor but I don't know much about how hall effect/magnetic keys feel nor do I know any really good companies outside of corsair.

Why wireless? For me, nothing but Wooting now. Optical is nice, i come from a K100 with Opticals, but they customizability if HE switches is something i dont want to miss ever again. 60HEv2 with Split spacebar is all i never knew i needed

That’s always going to a personal thing. Personally, I think Corsair’s board quality and features outpace Logitech and Razer. Razer and Corsair switch type is about the same quality (for OPX vs Analog Optical Gen 2). For this sub though, both are garbage tier. And I say that loving my K100 OPX that is collecting dust. There are MANY better switches and boards. Hall Effect is the current push, but optical isn’t too far behind if you don’t need “rapid trigger.” Wooting 80HE from a pure performance standpoint (irrelevant if achievable by a human) is probably the best gaming keyboard spec wise, but the build quality and feel is not perfect. Different boards and switches for different folks. If you like flashy RGB and Razer Synapse (honestly why for Synapse though), more power to you. If you don’t, there’s an ocean to explore.

Currently using a Corsair K100 with OPX switches. Love the board but I'm getting gear acquisition syndrome from all these new analog rapid trigger keyboards. I've narrowed it down to the Wooting 80HE, SteelSeries Apex Pro TKL(Gen 3) and Razer Hunstman v3 Pro TKL. The newest version of the Apex Pro is on sale for just £146 atm. I work in a store that has one on display so I know I like the feel of it. The only thing stopping me from pulling the trigger is all the people insisting that the Wooting is SO much better. The Huntsman is only £30 more. I understand the typing experience on it isn't great. The reason I'm considering it is because it has all the same features as the Wooting for much less and on paper it has the best switches of the three in terms of precision and reliability (I'm sure the difference is probably imperceptible). The Wooting obviously has great reviews, but £200 for a plastic board with no PBT keycaps and no wrist rest is... bold. If you want a metal one with all that stuff, there goes another £120, for things that are standard on both other boards. I know the Wooting is the best, but I'm not a keyboard enthusiast. Is it really \*that\* much better than the other high-end boards, or would I be paying for quality differences that my palette is too unrefined to appreciate?

300$ for a high end keyboard is not that much as you think. I've had 95 plat and now k100 optix and not a single issue. 2021.09.16 (MM/DD) and still going strong. Switched the keycaps to pudding ones for more rgb.

Its even more crazy if you think the brand new one that has built streamdeck (hate it or love it) and its still only 320 when a streamdeck itself is 100 and up.

Is the only difference the type of switches used (between the Pro and non-Pro)? How does this compare to my beloved k100?

Thanks! Sounds like if I like my current OPX K100 I should only look at the MGX Vanguard Pro version then

Unless you need/want wireless, K100 and it’s not even close, especially if you go certified refurbished for $125 - https://www.corsair.com/us/en/p/certified-refurbished/ch-912a014-na-rf/k100-rgb-mechanical-gaming-keyboard-cherry-mx-speed-black-refurbished-ch-912a014-na-rf
