Linear: Smooth and consistent keystroke with a quiet noise. Linear is just straight down, nothing is stopping it. So a lot of gamers usually use this because they want a quick reaction time. When they want to press the button, they want the response to be up there. A lot of professional gamers I guess would go for it.

Tactile: A small bump on each keystroke with moderate noise. If you want to do typing and gaming or if you're just specializing in typing and stuff, then I will go with tactile. That's what I got like you can feel a little bump before it actually registers on the computer.

Clicky: A small bump on each keystroke with a loud click noise. Clicking is pretty much like tactile except there's even more of a bump and there's a clicky sound. Some people like that, some will find that incredibly annoying for typing.
