My experience is most gaming keyboards are alike, biggest diference nowadays is the design.
If you like the design of a keyboard and you have the possibilty of trying it tand you like it, hen I would chose that
Quite sure the Logitech K120 isn't even considered for gaming and perfectly understood but I find it a lot nicer then the Steelseries 6GV2. Had to try the latter to see what the ''mechanical fuzz'' is about but I found this particular one waaaay to heavy and clumsy feeling.
What I would like to do is to make the K120 WASD keys more resistant to slippery. I'm thinking some sort of (cloth) stickers. Anyone any ideas?
The Razer BlackWidow Ultimate Stealth has MX Cherry Brown switches, which in my opinion are a good compromise between MX Cherry Blue, which may be best for typing, and MX Cherry Black/Red which may be best suited for FPS games.
I've been through blues, browns, blacks, and reds. For my preference I like the reds because they are just so light.
As for a keyboard, it's a bit overpriced but the Corsair K70 is what I use. Well built, simple design, decent backlighting (I got the black version specifically for the red backlighting, white/blue for me is just too distracting) and an ok wrist rest (not padded, just some kind of soft touch plastic/rubber).
There are so many key types and flavors to keyboards and what may be a great option for me might be a poor option for you, you need to try different switch types.
here are general things you should note when looking for a key, but you should still try them first in real life (only the ones I have tried):
Red: are considered better for gaming, mostly due to the fact that you easily and quickly (very low amount of force required) can press and repeat pressing that key, however they are liner and you can feel the actuation point. I really don't like them
Black: also liner, however require much more force to push and I generally don't like them, but I prefer them over reds
Blue: my personal favorite! mid-low force required but with a pretty accurate clicky feedback that let's you know you have passed the actuation point, however you have little to non indication of when the key press has been released.
Green: also one of my favorite, heavier than the blue with a strong and accurate clicky feedback for the actuation point, also a pretty nice indication of when the key has been released.
Brown: They are slightly heavier than the blue, but not nearly as heavy as the greens, the have a nice feedback but instead of a click they have a bump, the biggest difference is that the key is much quieter (almost as the blacks or reds) with a less accurate feedback than the blue (still great).
Should be noted that some gamers choose membrane keyboards because of the lower travel distance and therefor should reduce the delta T between the key press and the actuation (I think it's not really helpful, but I'm not a compeditive gamer.
After you chose your switch type, you need to choose the keyboard by design and features.
Example, you play a lot of MMO and you need a ton of macros.. or you need LED back-lit..
Do you want a tenkeyless or a full size keyboard?
wristrest is importent? you can get aftermarket ones if you want..
Are you interested in cool, minimalist stealthy keycaps like the CM storm quickfire stealth or the filco ninja(I can't attach photos yet, because I'm new at Head-Fi)
Also, If you have a pet. make sure to get a braided cable, and if possible a removable cable because they will chew your cable at some point...
The MX RGB looks to be awesome and of course it's announced right after I upgraded all of my keyboards to Ducky Shine 3's. Since my first post in this thread, I have refined my thoughts.
Gaming keyboards are a lot like headphones in that you need to make sure you're using the right one for the right job. For FPS competitive gaming, you want...
...and that's it. Illumination, game mode, and other bells and whistles are just worthless gimmicks.
The Leopold Tenkeyless Linear Touch Keyboard meets every one of those requirements and is, quite simply, the best keyboard for FPS competitive gaming.
I found that I was having far too many accidental presses with the Red, so I got the Black and now I'm in heaven. The tenkeyless is still an absolute must for FPS gaming still. I just can't get the movement I need in my wrists when my arms are as far apart as they are when using a full-sized keyboard. Full N-key Rollover continues to be a must. Playing in the dark also made me understand the importance of the illumination. That's why I went with the Ducky Shine 3 Tenkeyless with MX Blacks for my gaming keyboard and the Ducky Shine 3 Full-sized with MX Browns for my office keyboard.
The newish MX Greens, what absolute crap they are for gaming. WAY too much force needed on them and the tactile and audible identifiers just make them slow as balls. For typing, ehh. I'd still rather use browns for that. I see a point for tactile feedback, but not audible feedback.
Can't wait for these MX RGBs to hit the street next year. Will definitely be looking to pick up some sort of tenkeyless MX RGB Black keyboard at that time.
