I have 2 KB's currently;

Razer Blackwidow Tournament 2014 (Razer Green Switches)
Corsair K70 Vengeance (Cherry Red MX)

Blackwidow Razer green switches stays on my desk longer than the Corsair mainly because I like the tactile feedback on the razer switches. The noise doesn't really bother me but I can see why it would bother some (it's really loud). I wish it was backlit (tournament isn't, full kb is). Layout is great and I don't feel as if it cramps my hand.

Corsair...easily one of the best keyboards I've ever used. First time using red's and despite between twice the size of the Razer, it feels extremely light weight mainly because of the Cherry Red MX's, those keys will press if a fly sits on em. In QL, I play a lot of PQL/race and it's a breeze w/ red's, slightly tougher with the Razer.

My 2 cents
