I use a Ducky Year of the Dragon Limited, and I love it.
Red Switches, per-key backlighting.
Unfortunately, nearly impossible to find now.
I had a Filco Majestouch Ninja 2 TKL before that:

Awesome keyboard, red switches but not backlit.
A more common one I've used is the Razer Blackwidow.
I haven't tried their supposedly silent version, but mine was really loud.
I'm biased against most razer things, so I won't say much.
As for "what kind of switches", I can only speak for playing games, I don't actually type with mine, I have a dvorak typematrix for that (http://www.typematrix.com/).
Red switches work fine for me for things like FPSes, but I wouldn't pick them for some things, like MOBAS. Reds are sensitive enough that the weight of your finger can depress a key, which can be really bad if that key is your 3-minute cooldown ult.
