As per the whole "I like Smash Bros. cause you can make people fly", that concept in this game would be completely awful. Like PASBR and Super Smash Bros. are apples and oranges. When the game is about combos (like this), having your opponent fly across the map completely defeats any combo-based system. Plus you want to keep enemies close to keep hitting them for AP, and then eventually hit them with an AP attack.
I like Smash Bros. a lot but I can't say I like it more since the two games play so differently. It's kinda like comparing Marvel vs. Capcom to Super Smash Bros. You can't really do that.
Smash has a combo system despite higher than traditional knockback distance , what makes PSAS look and feel stale to a lot of people (other than the lack of content) is the lack of dynamic elements in gameplay. Most traditional 2D fighters get away with fewer of those because they have much more complex control schemes and mechanics. Smash has variable hitstun/knockback by percentage, slight influence in knockback angle by the victim, 6 tech options on knockdown, more mobility options (mostly the second game), higher character weight variety, and more differences between sweetspot and sourspot hitboxes leading to more uses for individual attacks and making every single hit of a combo a complex read. Jump Ultimate Stars (though it's not really considered much of a success) has a extremely diverse team building and assist system (granted the Big 3 are banned) and a ridiculous raw roster size to support it and compensate for simplified controls and slightly more linear character design.
PSAS really have much of this kind of stuff except for the kinda meh super meter system, and while it's cool that they tried something different instead of copying smash or using a generic health bar, they're going to need more and/or redesigned mechanics if they want the game to be interesting. Combos are fun to experiment with in training mode but once you reach a certain level of play there's only one optimal combo for meter or into super for every hit confirm.
