To be fair, quite a few of the Espada were meant to parallel certain Shinigami (e.g. Starrk to Shunsui, Harribel to Hitsugaya, Szayelaporro to Mayuri), and there were only 10 of them. Meanwhile, we've got at least 26 Sternritter who are all meant to be arrogant sociopaths due to how they were brought up in isolation with what they believe is a physical god as their leader - there's not much room for them showing compassion, humanity, or common decency like the Espada did, nor is there as much time if Kubo intends to make the pace faster than that of the Arrancar arc.
