Keyboards are a personal thing, like a musical instrument. You play one until you find the one that feels best to your hands. Same with a computer keyboard.
My preference? Old IBM p/s2 keyboards with a lot of click, because I'm a poor typist. I love the beasts. Our local schoolboard has a warehouse full of them. I date an IT tech from the county and she's scored me a couple of them for free. I'll need a few more. They're rebuildable, and some have nice long coil cords on them.
Next favorite (and harder to find): old Northgate keyboards, which were similar, but with the F keys to the left of the keyboard, not above.
Disadvantage: no Windows or menu keys, none of the Internet or sound control buttons.
For gaming, I use a Nostromo gamepad, so that doesn't matter one bit.
