1.
LDS - Easily my favourite Trek series. It has everything I could ask for: Charismatic & engaging characters, wonderful world-building (including expansion of the existing Trek Universe), great stories (with very little use of the reset button), new stuff & nostalgia, humour (very funny!), and Cetacean Ops (I love you, Kimolu and Matt)!!! Oh, and Rutherford

2.
DS9 - Knocked off my top spot by LDS, it has everything mentioned above except overly wacky humour, Cetacean Ops and Rutherford. But DS9 does have an astonishingly good cast - regular and guest alike - who easily elevate what could be rather bad episodes.
3.
ENT - Another great cast playing engaging characters (although Archer & Reed I can take or leave sometimes depending who's writing them), I enjoy about half ENT's run of episodes (none of the other half are terrible), and rather like the prequel set-up.
4.
VOY - A great premise that was never followed through on, and full of missed opportunities and reset buttons. Only a few genuinely likable, if somewhat underused, characters (Kes, Tuvok, Chakotay, B'Elanna & Paris), but some great episodes amongst the average and downright awful ones.
5.
TNG - Somewhat dated, and mostly rather dull (I'm not really a fan of the stage play-like set-up/stories) although there are some episodes that I love. And, like with VOY, only a handful of characters that I like: Picard, Troi, Crusher (Beverly, not Wesley), and Worf.
6.
TAS - I wondered whether to include TAS because I haven't seen all the episodes, but despite not liking the cheapo animation style or many of the TOS characters, it did expand the TOS-era universe and introduced some wonderful aliens and ships.
7.
TOS - It's just too dated for me to really get into, and it's not helped because I really don't like the Kirk and Spock characters. However, I love the first four TOS movies - even Kirk and Spock!
8.
DSC - Not for me. I didn't engage with the main characters (except for Saru, Tilly, and Lorca before the MU reveal), and I don't like the filming style. Although, I did watch it through to the end of season three (I was kind of relieved that season four was pulled from/never made it to Netflix), and it did introduce the gorgeous and charismatic Anson Mount Pike

along with the slightly less gorgeous Ethan Peck Spock & Rebecca Romijn Number One. I shall never forgive DSC for killing Airiam, though

9.
PIC - Oh, dear... I thought it was all rather messy and self indulgent. I couldn't finish season two as I just had no interest in the story or characters. One thing I did like was the Romulan Pixmit/Pikhmit cards from S1 - they were amazing!
I've not yet seen SNW or PRO (or all the Short Treks) as they're not on telly here in the UK yet, but from the trailers, clips and behind the scenes stuff I've seen, I think I'll enjoy them very much!
