The question infers, could it be that Quarry actually would beat Chuvalo most times out of 10 fights for example? Yes Chuvalo had some power, and would always stay in there, but would Quarry take it most times out of 10, rather than being taken out as he was in their sole fight?
I think so. If the best version of Quarry shows up, i can see him outpointing Chuvalo more often than not. But given how durable Chuvalo was, i don't think it will ever be an easy outing for Quarry.
