I'm actively using vbulletin, so that's obviously my preference.

From my research you should look into pricing. While it most likely will not break your decision, be aware infopop is rather notorious for charging nice fees (@100+) for updates. Jelsoft (makers of vb) have a nice $30/year for all updates and new versions. Vb seems to scale better as well. Plus feature wise ubb is nowhere near a match.
