Which computer company builds the best workstation???
Don't switch to Pro/E unless you have a very compelling reason to spend 3-5 times as much money and get less work done. If your designs are complex enough to merit a switch to Pro/E, you may as well use Unigraphics and have the best available without being roped into PTC's poduct line.
I have logged several thousand hours on each Pro/E, UG, and SolidWorks. SolidWorks is just fine for 98% of the CAD work I have encountered, plus the support has been outstanding.
I would like to know what type of product you are designing. It would help me make a better recommendation.
