Black Adam should win based on his abilities.
Even with it WWH, he starting functional strength is lower and he's significantly less durable.
BA has true super speed (as per low level Flash) and the power of flight.
He should be able to simply fly through the Hulk, leaping a 2 foot wide gaping hole in his chest and take the corpse up in to the upper atmosphere before he regenerates and throw him in to space.
Even if Hulk went to hit BA, BA's speed virtually gurantees that Hulk will miss.
