Yeah, I would say he Ginobili is a much better athlete. Not that it would necessarily translate to being a better tennis player. One difference between the sports is that being tall and somewhat athletic makes you automatically a pretty good basketball player; having four inches on a guy and being able to palm a ball are pretty big advantages in basketball, whereas in tennis it is more of a double edged sword. This is obviously not the case in Tennis, the advantages are not as obvious. Still, given the same athletic ability, you would probably rather have a couple of extra inches.
