Vader is more powerful in the force.
Vader and Mace are likely even in speed. Though tbh I'm not the best judge of speed feats.
Vader is more durable.
Endurance is debatable.
Vader is stronger.
Vader and Mace should be about as skilled considering the various opponents they've faced.
Vader's suit restricts his mobility and Mace has shatterpoint and possibly Vaapad from which to draw from.
It's a close fight but I'd favor Vader.

It did but it probably only gives him about as much extra physical endurance as the force would have when he was whole.
I just viewed the Vader Down thread though and if we take those feats into account he should hold an edge over Mace in endurance.
