Nope, manga counterpart was truly horrid. For example, check out the differences in expressions when Gray is about to cast Iced Shell. Imo, Mashima tried a bit too hard to convince us that he is actually Deliora, so much so that the final reveal just felt stupid, even though him being Deliora is the one that doesn't make much sense.
