I really liked Starrk. He was calm and didn't like fighting, and only performed his orders. I feel sorry for his death because he only joined Aizen because he wanted to find friends who were strong enough to be near him without crumbling away, like all ordinary hollows did, and Aizen could offer that.

I also feel sorry for Ulquiorra's death, cos even though he was cold and only believed in the things he could see because he only had the sense of sight when he was a hollow, he discovered what a heart was and started to gain interest in humans just before he died.

Both of them were strong, and Ulquiorra was immensely powerful in his Resurrectión: Segunda Etapa. They could have become good allies if they had survived. Starrk had just the same kind of personality as Kyôraku, maybe he could have become a good friend of him and Ukitake. They all liked peace and didn't want to fight. And Ulquiorra could have learned more about human emotions and maybe become friends with at least Orihime.

Both would have been valuable allies in the war against the Wandenreich, as they were among the strongest Arrancars. And the Stern Ritters can only steal Bankai, they cannot steal a Resurrectión, as far as we know.
