I use Illustrator to make all my icons now, since I've switched to using SVG for high-res display support. Wouldn't try to use it for mocking up an entire site though; FW is much more suited to that. Working with Illustrator for large numbers of shapes and gradients is insanely inefficient. Illustrator is for precision work and advanced vector shapes, while FW is for throwing a bunch of (commonly shaped) shit at a wall and seeing what sticks, and for that there's none better.
