So for the purposes of this thread we're looking at only the first season of each show. As a clarification, I'm not bothering with TAS (just calling that season four of TOS). You can add Prodigy or not. It's not done yet, so I'm not sure if that's fair.
For me, in descending order:
1. SNW. They just hit it out of the park.
2. TOS. Not just because it introduced us to the world, but because so much of it was fantastic.
3. LD. Started off rocky, but it got consistently better.
4. VOY. Yeah, it's on the lower end of Trek shows overall, but it started fairly well.
5. DS9. It only got good, really, in season 2 or 3. But this one did give us Duet.
6. ENT. Not as bad as I remember.
7. TNG. Just not good.
8. PIC. Not very coherent.
9. DIS. Natch.
