I personally think that Inventor is better, but I only have experience with AI, so it may be a tad inaccurate.

I like the menu setup and view control in AI, but putting parts into assemblies is a bit complicated. (This is coming from someone who has only used Sketchup)

Anyway, Inventor is free, so I recommend it for new teams that are unlikely to get a sponsorship from Solidworks.
