I've used Pro-E occasionally, but when I tried to do it again, it was harder...

I learned Inventor first, then when I had a Solidworks/design class, my section focused on the design and the other section went for the Solidworks. If I hadn't known Inventor, I would have been pretty well lost. Other students were lost and I had to help them. In terms of interface, Inventor (the versions I played with) is more compact; for example, Solidworks has two buttons for extrusions (one for cutting, one for adding material), while Inventor has one (select inside the box).
