The MX switches are like toys, in my limited experience. Trying out the browns after my scissor/dome apple keyboard, the plasticy bump was appalling.
So I went down to Fry's and tried the various Cherry switches. I more-or-less fell for the blues, because they are so much crisper than the browns.
But I used to use a buckling spring keyboard, and it has its charms, for sure. Loud, hard to bottom out, bouncy. And cheap!
It's tough, though, finding the "right" keyboard. I'd like a backlit one, but almost all the companies put the symbols (the most important part) beneath the number, so they aren't well illuminated. The ones that do the lettering right are Deck, which only has clear switches in tactile (WHY?) and the new Noppoo. But the Noppoo isn't Mac-compatible (WHY?). At least the Ducky has DIP switches...
I tried the Rosewill RK-9100BR and it was fine, to the extent of my knowledge. There was an issue with the spacebar making a clicking noise, but the switches are mounted to a metal plate and everything seemed in order. And it's $50 less than the Ducky. It's out of stock, but it's what I'm looking at. And I've never understood why the Race/Pokers were so popular... PCB mounted? ¿Que?
So the best keyboard for me is likely the Rosewill RK-9100. I may "settle" for the CM Storm QuickTrigger Whatever TKL with the Blues and the backlight that just came out ($90), or "splurge" on a Ducky Shine II.
But these probably aren't the best keyboards for anyone else, in general. Frankly, listening to some of the gamers, I think they'd be best off just getting a membrane board with NKRO! So it's hard to think about these issues when the hype gets going. Hopefully exposure to my "process" will help others formulate theirs.
