I simply can't agree with that. Looking back, Zoro may have started displaying signs of Haki before Luffy (with his demon aura and all) but I have yet to see anything from him that could cause an entire arena of people to faint.

Luffy's haki maybe still be in infancy, but compared to zoro, the difference is indeed that of captain and subordinate.
