Best Smash in the game?

[Got4n]

Who do you think deserves this title?
In my opinion, I'm hesitating between Mario's upsmash (if reverse jump cancelled, it's super hard to punish) or Meta Knight fsmash (this thing when shielded pushes the opponent SUPER FAR and kills super early)

THIS THREAD us already discussing best moves of each type. They will eventually get into Smashes; though they all will be divided by category (Up/Side/Down) and they may take some time to get into them.
