It is just lighter and more efficieant than the cast wheel. It will generally give you better spool up, and can move more air at slower speeds, so more torque, around 100 ft-lbs more. Horsepower gains will be minimal at best.
If you are just looking for reliability, the pmax may be the most reliable VGT turbo out there, the unison ring is revised, so it is less likely to get sticky and cause issues.
I also think that the earlier turbos, 03-early 04, are more reliable but that is just my opinion based on observation. I have no hard facts to back that statement up.
