I have used Inventor for about three years now and I like it a lot. I have not really used SW (at all) and my opinion is definitely biased, but I have been using ADI since my freshman year in my CAD class, and have found that it can do amazing things. However, the animation can be a pain (I don't know what it's like for SW) and putting sub-assemblies into complete assemblies can also be a bit annoying, especially if you need them to move. Overall though, I would give ADI two thumbs up.
