There are tasks we could use quantum computers for that would be practically impossible otherwise. And there are tasks that we could do a bit faster on a quantum computer, but it would still be reasonable to use a classical one. 'advantage' could mean either of those. I think it's the absolute dominance over classical computers in the former that people are trying to invoke with 'supremacy'.

The need to use such tainted words is probably an inevitable consequence of trying to explain that one thing is so much better than another. Those words will have been used before in contexts that we don't agree with. Maybe 'transcendence' gets away with it by having kinda spiritual connotations, but that probably makes it a bad fit for science.

Anyways, 'advantage' seems to be the primary option besides supremacy and it isn't too bad. My reservations with it aren't strong enough to try and champion anything else.
