I use plain-jane vi on Unix and gvim on Windows. (When I was on the Mac, I used BBEdit.) Frankly, I vastly prefer plane-jain vi. I detest colorization and pre-emptive tabbing. (Of course, this could be because I was forced to use vi for years and am crufty and crochety.)

As for IDE features ... I use three things:

map q :e #[Ctrl]-V[Enter]
map v :!perl -wc %[Ctrl]-V[Enter]
map V :!perl %[Ctrl]-V[Enter]
[download]

That's it. For the rest, I use vi's own editing features. All I need is two buffers, compile, and execute. 90% of the time, I don't ever use the shell. (This is another reason I don't like gvim.)
