My favorite switches to type on are buckling spring ala my Model M. Second to that, I currently prefer my Cherry Blues, though they feel just a little too light for me, as I bottom them out pretty heavily. Part of that is because I used fake White ALPS "fukka" switches for about 2 years, which are I think are pretty stiff.
I currently game with Brown Switches. I liked the Black ALPS on my ABS M1 a lot for gaming, but I wanted a TKL with more key cap options, so I went to the Cherry Browns.
I don't really like typing on my Browns, though, because there is no click. I just really don't like a typing experience without that audible click (not just bottoming out). There is zero chance of my typing on a switch without a tactile bump. In the same light, I could never game with an audible click, because that would drive me crazy.
I'm getting a CM Storm with Reds today. I'll be gaming on those for at least a week to see if I like them more than the Browns. Hopefully, they just feel nice and natural right away, though.

P.S. I don't really play RTS's anymore. Mainly FPS for MP (Nuclear Dawn FTW!) and any genre singe-player games.
