I don't like browns all that much, but they're still nicer to use than linear switches, IMO. Clears are much nicer if you can get used to the heavier springs or do an ergo mod -- they're a lot more tactile, and tactility is what I seem to like in my switches.
Blues are good. I've never had any real issues with them in casual FPS, but when I play more serious matches, I have been asked to change my keyboard so they aren't heard over voice chat. I have occasionally missed a press with them that I wouldn't have missed with my browns or clears, but only rarely. Other issue I've had with blues is that if people are trying to sleep in the same room, I can't use that board.
For typing/coding, I prefer blues immensely to browns, although now that I've used clears for a while I'm wanting to mod them with heavier springs and make greens.
My personal recommendation would be to use blues, but it all comes down to what you prefer. The best option is always to see if you can borrow a keyboard and try it out for a period of time (a week maybe). Or if you're lucky enough to live near a store that would allow you to return or exchange a board, you could try buying a board with blues, and later exchanging it for the browns if you find you don't enjoy the blues or are having trouble with them.
