Ultimately Orlando's version of the origin was definitely better than how it was presented by Finch - Abnett's was just the base of "Donna was created as a weapon" without going further into the information about it - but I think that this point it's just better if we go back to her pre-Crisis origin. Not only do we have a situation where "everything matters" but it's the first time in a long time that Diana could've actually saved a baby Donna Troy from a fire and taken her back to Themyscira without it messing anything up since before Flashpoint at the least, and even then I might be willing to say since before the Crisis itself. It's the most simple origin for Donna, and it's the one being used in the show so it's probably the most well-known at this point. I'd like to work the Titans of Myth in there some way because "Who is Wonder Girl?" is after all the third or fourth most popular Titans story in the first place, so having it maintained is probably a good idea.
