Price. He gets hurt by weak ass cuffing blows, and stiff legged from the same. Wilder might do the stanky leg here and there but he always recovers soon after. Price has a Herbie Hide level chin.
I think Price's main problem isn't even the jaw (which is abysmal). It's probably as bad as Wilder's. But Wilder has decent conditioning, he can box 12 rounds and he can run around to ring to hide his jaw, but still be dangerous on the backfoot. Price gasses out after 4-5 rounds. I mean that's just appalling for a professional athlete. He simply gives up after he feels his stamina is gone.
