There's also butterfly joints so he has extended range of movement for his arms. The ab crunch is slightly better but the waist rotation is the big plus over Part 3 SP.
They also threw in joints for his shoulder armor so you don't have to worry about warping those for high punches like in Part 3 SP.
The only gripe that comes across people is the headsculpt and colors but Medicos essentially made a SP 2.0 for Part IV.
