Blues are the best for typing but the browns are quieter. I'm typing this on browns after coming from blues. Wish I had stuck with blues to be honest. If you want to type as fast as possible, blues are it. Reds however are not very good for typing. I would personally say get blues if you can. If not get browns. But if you only want to game and that is it, reds are fine. But if you need to type even an essay, browns are where you should be if you can't get blues.
I know that made no sense so:
Blues: Get these if possible. Beware they are loud. If you don't need to type essays or anything, these don't have a huge point.
Browns: Get these if noise is an issue. If not get blues.
Reds: I would never get these personally but if you game exclusively, I don't think there would be an issue.
