I prefer Eclipse with VI plugin. You get the best of both worlds. And if I'm not happy with the vi plugin implementation, I can always continue editing in actual VIM by typing :vi in Eclipse. All, that being said, I have heavily customized VIM with ctags, cscope, Command+T plugin and taglist. Command+T alone is really worth it, you can open any file in the entire project structure by just typing a few letters (just like Eclipse's CTRL+SHIFT+t, but works on any file type). With all these I can navigate code, and edit pretty much like I am in Eclipse, but unlike Eclipse this combo works for C,C++, Ruby, Python, Perl, Javascript etc. as well.
