It is a question that truly just comes down to preference and feel imho.
For 4 years I have been using the Razer Blackwidow Ultimate 2013 model with cherry MX blue switches, and have always LOVED them, but started to wonder if there was a better keyswitch type suited for WoW. I just bought and immediately returned the Corsair K95 with Brown switches because it just felt too soft. I think I still need to feel out Clears and Blacks because I am big fan of the bump and more resistance, but I could really care less about the *click*. So whats your preference, and why?!
