Well I own every switch type (blues, browns, reds, and clears) expect for blacks. I have tried them out in a local store and they were too stiff for my likings.
Anyways, a switch type isn't going to help you type faster nor game better. It's all just personal preference and different feelings. I have never had a problem gaming on my blues and I play a lot of different type of games. Anything from FPS to RTS to MMO. Double tapping on them is not an issue, well for me anyways..
But just to give you an idea on how the blues feel in comparison to the browns, hmm the browns are slightly lighter than the blues but not by much. The tactile bump on the bllues are much sharper. I can barely feel it on my browns. And obviously the blues provide a "click."
And yeah Filco>xarmor no questions asked lol.
