Superboy Prime vs Popeye the Sailor.
They both seem capable of doing impossable things by punching and are insanely fast and durable. I would say that the Brat of Steel clearly has the edge in mobility, and Popeye probably couldn't move a planet without first ingesting his spinach. Just the same, Popeye is far more unpredictable and is a far more experienced fighter.
