Best Linux GUI for programmers?

Currently running 9.10 with Gnome on my thinkpad x200. I'd like to get a new GUI, which one is best for programming? I'm considering Rat poison but I thought it would be worth getting advice from /prog/ before I commit. Thanks.

I don't see the value of not being assholes, personally, and >>3 was a helpful answer. The most helpful answer you deserve, anyway, and certainly much more helpful than just saying ``xmonad'' or ``dwm''.

Hint: the gist of it was ``you don't know enough to make a sensible decision, look it up''.
