I bought a K95 with Red switches before, learned that I was not a fan of red switches. Feels a little too mushy for me because the lack of a click and the springiness. I LOVED the typing experience of Blue switches, but none of the keyboards at the store near me (Frys) had it. Ended up going with Brown switches on a Coolermaster keyboard, and I am very happy with it.
When they say Red switches are good for gaming, what they mean is that you repeat keystrokes fastest with these because they require the least amount of travel for the keystroke to be accepted. When they say Blue switches are the best for typing, what they mean is that you have to push it all the way past a point where it "clicks" audibly, and you also feel the click which gives you good tactile feedback. Brown switches also have to be pushed beyond a certain point and you will get both an audible and tactile "click," but it will be less pronounced than with Blue keys.
Bottom line: In my opinion, Brown is probably the best for most people, and better for gaming than Blue. Blue is great if you type a lot and don't care about noise. Red I wouldn't go with at all.
