I lost interest in Discovery very early in season one. I made a stab at watching season two and lost interest again, and from everything I hear it never got any better, so I never bothered with anything else. I tried to sick it out with Picard in its first season, but it got so awful I stopped watching. Tried the same thing for season two, and the same thing happened. Season three was actually pretty decent, so if you want to watch Picard, I'd just watch that one.
Lower Decks is pretty fun, and it gets better after the first season. My main issue with it is that the characters all constantly reference things that happened in previous shows as though they're Star Trek fans, and not people who actually live in the world of Star Trek. But that said, it's surprisingly good.
Strange New Worlds is a very mixed bag for me. There are some very good episodes that have that pulpy TOS feel. But there are some episodes that use outright tired sitcom plots, and those are very weak for me. It also has the same problem for me that Disco and Picard have where everyone acts really casually with each other, and everyone is everyone else's best friend, and there's no sense of military hierarchy or that a Federation starship is a serious environment. (Ironically Lower Decks is the new Trek show that has this problem the least.) The show also insists that Spock is the same character Leonard Nemoy played, but he's so completely different that I just think of him as a different version of Spock.
