Those are the three main switches. Some people will argue that blacks are "gaming" switches because of the release/actuation point being at the same point while blues are different which somehow hurts their performance when they try to double tap. In reality it comes down to personal preference. I love my Black Widow with the Cherry Blues but some people don't like them. It would be nice to try the browns since they wouldnt be as loud but that's more money :/
This. Blues and browns have a bump, which lets you know the switch has actuated, and theres no need to completely bottom the key out, because the bump lets you know that the key has been pressed. This is helpful for Touch typing. The only difference between the two is that the blues also have a clicking mechanism which makes an audible click when the switch actuates. Some people like it, some don't, it's all personal preference. My advice would be to go to a retail store and try out the switches. (Some Best Buy's carry the Razer Blackwidow, which has Blues, and the boxes have holes in them so you can try them out. Browns and blacks might be a little harder to track down, but if you have a Fry's or Microcenter they might have a few that you can try out)
Blacks are a linear switch, meaning there is no bump and no clicking noise, just a straight constant force from the starting point all the way to the bottom. They are usually defined as the "gaming switch", because theres no bump or click to get in your way, but many people prefer the browns/bues to them. Again, it's all personal preference. The best advice anyone can give is to actually try out the switches for yourself, but again it's not always the easiest thing to do.
