My only complaint about that, is that I feel that Aizen was too overpowered after fusing with the Hôgyoku, taking out Shinji, Shunsui, Sui-Fêng and Tôshirô with no trouble at all, and fighting Kisuke, Yoruichi and Isshin at the same time without even breaking a sweat.

I know the Hôgyoku gave him powers far beyond his Shinigami limit, but the way it was portrayed in the anime (at least), made it seem too much for me.
