They’re both great and serve different purposes. The Orville is a more light hearted tribute to 90s TV sci-fi, albeit one that’s become more serious and built up it’s own universe and tone as it’s three series went on. Trek, as it exists today, is taking various Trek tropes and styles and trying to update them to modern times, be that via deconstruction in Lower Decks, nostalgic big-budget adventures in Picard, or introducing more modern character development and serialisation in Dis and SNW. Some times it succeeds, sometimes is doesn’t.
