The spring is the main feature for me. Takes away lots of wear and tear on the frame and the action is noticeably smoother.
Being left handed (At least when it comes to shooting) the ambidextrous mag release would be nice.

I think for the slight increase in cost I'd like to have thegen4, just nobody has any!!!
