I personally prefer mechanical keyboards, but not everyone does.
For me, the Ducky Shining takes the cake - Backlit in red/green/blue/white, comes in red/brown/black/blue switches.
From there I would look at Deck Legend boards, Filcos, and maybe on a budget the BW.
If you don't like Mech boards, the Logitech G19 is pretty neat. http://www.overclock.net/t/491752/mechanical-keyboard-guide/0_30#post_6025204
