Thank you guys for your thoughts, it helped shape my modeling preferences a lot.
I have used CATIA and also NX at some stage in product development, and i still prefer by far to use Alias when it comes to surfacing. I find i have more control over each step towards building geometry. But to each his own i guess.
I believe that as Alias surfaces are dependent on the quality of the curves from which they are built upon, same goes for external CAD systems; if Alias data is crap, other software will do a bad job of “fixing” it
