User blog comment:Uraharattack/Starrk's classification as a hollow?/@comment-1387259-20130820163125/@comment-11051098-20130825102309

One thing I think we can conclude, is that if Harribel was a Vasto Lorde before Aizen recruited her, Baraggan and Starrk must have definitely been so too. They were ranked higher than her, and as it's implied, were stronger.

I feel that Ulquiorra should have been a Vasto Lorde too. At least in his Segunda Etapa-form. I feel that his second stage made him at least equal to Harribel in power, although that can't be said for sure. He dominated Ichigo before Hollow Ichigo took over, and Harribel mostly appeared to be equal to Hitsugaya, if not barely stronger.

But, Harribel was kept off by 1 captain and 2 former lieutenants. Maybe she didn't use her full power against them, but I feel that if Ulquiorra in his 2nd form had been in her place, he would have dominated them without much effort.
