I've played some Starcraft 2 lately on a black Cherry (from the sig) and it had some drawbacks. Actually, typing on it felt much better than playing SC2. I felt I constantly needed to mind my keyboard. Tactile feedback gives you some kind of subjective security, I guess (one I can do without when typing and even appreciate not wasting time on the distinct actuation, but curiously not when gaming). Barring this factor, the blacks would probably be better or even much better.
Oh, and I would really suggest playing around with an old IBM Model M (or even the Dell AT101W that someone mentioned) if you can find one somewhere for a couple of bucks like people do. It's far from NKRO for all I know but it can be great for RTS gaming.
