The One Above All is really not someone that you want to fight considering how powerful he is supposed to be. If he even gets a fraction of the feats that he should be capable of…the One Above All will be a tough fighter to beat. That being said, we haven’t seen any true feats for the guy yet so Ban can easily take the win here. His robot is simply too powerful to stop. Ban wins.

Toaa stomps on ban. Toaa created the marvel multiverse while ban can’t even create a single universe and destroy it. The whole seven deadly sins can’t defeat Toaa he’s omnipotent (All Powerful) omniscient (all knowing) and omnipresent (everywhere)
One Above All wouldn’t be able to keep up though because he has no feats yet. Also, this is Ban from LBX and not the Deadly Sins so he has Achilles at the ready to get those wins
