Mechanical Keyboards

Might as well help get this channel off to a flying start!

What's your favourite switch (key type) and why? What would you like to try but haven't yet and what have you tried but wasn't for you?

They're noisy, clacky, impossible to use in an office, in your house without headphones, perhaps even annoying neighbours, need effort to make them work on USB, so why do people love them so much?

I've tested two. Didn't like them because sometimes if you don't hit the keys head on, they move a bit to the side with the spring and that's jarring on your fingers.

Where do you stand on the debate?

Also, first post, so what better a topic!
