Meh, I don't really look forward to watching either. I agree comparisons should stop though but I think they are in side by side leagues. Comparing a silly show to a serious show, both failing to succeed in different ways. Orville is more fun but not nearly as fun as straight comedies, Discovery is interesting but not nearly as interesting as better dramas. Both are okay shows that are lacking something crucial, equally good overall.
You know the show The Good Place, where there's that one woman who is in the Medium Place, where everything is okay but not so great? In the Medium Place, there are probably full series box sets of both The Orville and Discovery.
