Yep they're pretty similar, though I don't really see why Subaru's is more questionable. Emilia is pretty much been the only person who has support him thoughout the story thus far without obligations. She's even put aside her more important/urgent interests help to him and others almost to her detriment. For him that is rare kind of person and is that trait that basically saved him. Like how Rem fell Subaru's heroic side, Subaru fell for Emilia's highly empathic nature. He's someone who has directly benefited from that trait multiple times and continues to do so even now. She is a hero to him.
