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.

Since you think ``Linux'' is synonymous with ``Ubanto'' and are asking about a ``GUI'' rather than a window manager, I'm going to say you need to stick with GNOME for another while. I don't think anyone feels like helping an idiot set up a tiling window manager.

Those aren't even the same class of things.
