To answer your question it would be dwight howard simply because he has youth over shaq. And we have all seen dwight dunk on shaq many times two
and another reason why is dwight got defensive player of the year and Shaq doesn't start on the cavs and he bearly does anything i think he should go back to the suns or the lakers.
it depends, right now dwight, but if you mean year for year? shaq, as much as i wanna see dwight do better than other big name centers, shaq outdid dwight, just look at shaq's numbers when he played in orlando, in fact, heres the link
dwights nice, but shaq had him on scoring and blocks, theyre about equal on rebounding, and all you can say dwight beats shaq in is FG% of course, shaq was being covered by a lot of big name centers back then(alonzo mourning, hakeem olajuwon,david robinson,dikembe mutumbo to name a few)
