Given (effectively) unlimited resources within base distance, Zerg undoubtedly have a fairly substantial advantage and will probably win. Assuming comparable player skills, of course.

Their remax time is 1/3-1/4 that of Protoss/Terran, they can tech-switch near instantaneously, and they have some of the most powerful endgame meta. This was true for SC1 and Brood War, and it's even more true for current SC2.
