I'm about to buy my first mechanical keyboard (because I'm getting sick and tired of sore finger tips on this lousy flat-key wireless piece of crap) and I keep going back and forth between the blue and brown switches. I'll probably only buy one keyboard, so this decision is bothering me - but without being able to test them I guess I have no idea which one is better for me - or if it even matters.
Brown seems like a happy medium. I don't think you can go wrong with that. Blue might be a little less appropriate for gaming and loud.
