Wrong.
DOS Doomsday showed 0 regenerative abilities.
We have seen Banner get 80% of his skin taken off and regenerate...as well as Banner getting shot in the head and instantaneously regenerating before the effects of death.
DOS Doomsday only showed Superman like-durabililty, and his modified Kryptonian dna kicks in and strengthens him AFTER being killed - Not during a battle or he would have killed Superman even faster, as well as lived through the encounter to continue his devastation of Metropolis.
Hulk wins majority.
