Keyboard enthusiast will consider Cherrry MX switches to be the best all around switches. That being said, the Corsiar k70, k65 or k95 have been claimed by many to be one of the best out there. The differences of the k65, 70, and 95 is the 65 is 10 keyless, the 70 is standard, and the 95 has a lineup of macro buttons on the side. those all are made in cherry red, brown, and blues. Reds are considered to be the gaming switch as they have no tactile bump with linear movement. Browns are the most popular for typing as they have bump and have a loud clickey sound, I have no experience with blues however i hear they are similar to browns.
