SWUSER: I don't mean to sound too harsh - and somebody please Red Flag me if I cross the line - but if you've really "used inventor, thinkdesign, pro-e, solidedge, Alias Maya, Alias studiotool, 3dmax and catia over the last year", along with SolidWorks, it seems like your usage was likely too superficial to have a strong handle on what features are/are not present from one package to another.
On the other hand, maybe you're just a super-duper CAD expert.
Not being an multi-platform expert (though I've used SE & INV along with SWX, all at different release stages), I'm eagerly looking forward to your comparative assessment.
