I mostly use IR_black for vim and emacs, that's definitely a classic. But I'm also quite fond of a custom scheme I made; the colors mostly come from Textmate's Made of Code scheme. Here's a screenshot:
If anyone is interested, the theme is here:

The .vim file started out as IR_black, I just hacked at the colors until I was satisfied, so the code's not clean or anything :)
[I also have a OS X terminal theme to go with it, and an emacs version.]
