Before I say anything, I'll say this:
As long as your keyboard works, you can use it at the top skill levels. It's all about personal preference.All this information and much more is available on the Deskthority Wiki:
http://deskthority.net/wiki/Main_PageCherry MX Blue switches are not particularly good for anything that requires fast key actuation. They are generally considered the best switches for typists/programmers and anyone else who primarily uses their keyboard for entering a lot of text. However, because of their two part construction it makes it much harder to minimize the travel distance when pressing the key. Blues do have a lighter actuation force than Blacks do, but not quite as light as Reds or Browns.
MX Blue - Tactile, Clicky, 50 cN actuation force
MX Black - Linear, 60 cN actuation force
MX Brown - Tactile, 45 cN actuation force
Mx Red - Linear, 45 cN actuation force
I should point out that Reds are harder to locate than the others, and
Here are some animations. Notice how the Blue has a two part construction. Also notice how the Brown has a similar looking bump on the plastic slider, where the black and red don't:
EDIT: Oops, originally had blues listed as 80 cN. Thanks Drace.
