I don't think you mentioned this yet, but Dark Pit has lower knockback. This is clearly evident when playing Multiman Smash. So I think it was more damage for lower knockback (Shulk does this so it's possible)

Dark Pit's Side Special also has electrical properties. Not that it means much...

Also, Dark Pit has much lower recovery jumps. Pit flies much higher than him.
