Can we just cut the shit here and not pretend like Surfer doesn't get hit/tagged in damn near every single one of his fights?
Along with being a peer to Superman in strength, Teth's punches carry the added bonus of being magically charged, which Surfer won't just shrug off. Not to mention, BA doesn't have any weaknesses to exploit.
The idea of Surfer winning 10/10, or even 9/10, is absolutely ridiculous given both of their histories and track records against characters of this level.
