Megaton punch? Useless.
Falcon Punch? Not even in the same league.
Kidd’s Commander-Powered-By-Starstone-Bigger-Than-Your-House-Twice-Over Punch is the most awesome. Only thing that even comes close is One Punch Man but I’d have to know something about that other than the name to know if he’s even 1/3 as cool as Kidd.
