Actually, they both do the same.

Both 1-up Mushrooms and Support moves can be used on a fallen ally to bring them back and if they do, their target is back up to half health. One thing to consider, after bringing the ally back, the 1-up gives them Second Wind, so they can do two actions on the turn after they are brought back.
