I would say only Doc's tbh. Luigi's is a very good USmash but its extended hitbox comes with a sourspot.Mario's usmash isn't much safer than other anti-landing usmashes like Rosa's, Cloud's, Tink, Yoshi, etc... It's just mario has no aerial kill move (relevant to the landing chain anyway) so he's trying to lead them to the ground for usmash more than those other characters which can kill them much more consistently in the air. Any added safeness likely stems from this.
Truly, mario would be way better over with luigi or doc's usmash.
Doc just takes the best of Luigi (longer hit duration but Doc's has a better hitbox even) and the best of Mario (no sourspot) and then cranks it up even FURTHER by having superior knockback growth and MORE damage than Mario's, making the less BKB Doc's USmash has not really a problem as it's still much much stronger. It's really an insane move, don't give it to anyone with a runspeed of 1.5 or higher. That's how good Doc USmash is.
