Which of the two are a more effective counter to a Zaul team

Currently, the faster Zaul team will almost always win.

In theory, Nihilus should also be an effective counter since he prevents his Sith teammates from critting, which in turn reduces how often his Zaul opponents will stealth/gain TM. In practice, I'm not sure how well this will actually work since no one on my shard runs a Nihilus lead and I haven't bothered to zeta him yet.
