I use and love both, together and apart. Vim has the advantage of being portable and installed everywhere. I can also create a new file quickly, easier than IJ. IJ has great Perl support and, the main reason I use it, a sane integrated Git GUI, the only one I've been able to use without tearing my hair out. Because I'm freegan, I also get free entertainment in the form of IJ's "basic" support for js, html, css.
