I've always used solidworks, and for me, it's definately the easier of the two.

Solidworks is more than just modeling software, it can quickly do weight calculations, stress calculations, even heat transfer and such =D

Also, it is very good at importing nearly any type of external data, and it can export in many filetypes.

I also find it very userfriendly, and I like the general interface more.
