Multiversus is a very different game to NASB, I don't get why you'd single them out for comparison, even in good faith, without also putting games like Rivals of Aether; Icons; and Rushdown Revolt in the comparison - one is a team fighter with characters from all mediums and a focus on new, relevant characters and easter eggs + callbacks to please fans; while the other is an "anime" platform fighter exclusively featuring animated children's television characters with a focus on decades-long nostalgia and competitive play. One can't really be better than the other when they're not even aiming for the same goal. It's equivalent to comparing Super Mario 64 to Crash Bandicoot.
