User blog comment:Stark373/Was Ulquiorra the most powerfull Espada?/@comment-27256136-20151120211135/@comment-5398287-20151121001520

Having a second Resurreccion doesn't automatically equate to Ulquiorra being more powerful than Starrk. He was likely stronger than Harribel and Baraggan, but Starrk matched Shunsui, now the Captain-Commander, blow-for-blow, even intellectually using his Shikai powers against him (something Lille didn't manage), only losing because Shunsui managed to outwit him. On top of that, he was the fastest Espada (Zommari ain't shit), had incredible swordsmanship skills and Ceros, and of course had Reiatsu powerful enough to kill weaker beings just by being near them, something only Aizen topped much later. So going by evidence from the series, he was still likely stronger than Segunda Etapa Ulquiorra.
