Both Ophis and Lilith seem more inclined to do what Issei says though. Ophis even said that she wouldn't fight because Issei told her not to.

Zen'oh seems more inclined to do just whatever he wants, like a spoiled child, Ophis is more like a well-behaved child. Zen'oh also doesn't really seem like the person who would step in to save Goku, but Ophis even revived Issei when he died.
