I'm honestly very bad at articulating myself, aa - but TOS has my heart because it's the first of the series I've actively pursued. And come on it's TOS - it's a lot of fun, the plots still ring with importance, and I adore the entire cast (especially Spock, my darling, green child - and Uhura's a fantastic role model for people like me).

I grew up with Trek in the background, my dad watched The Next Generation a lot when I was a kid, so there's a real nostalgic feeling that comes with the series overall for me. I'm actually getting back to my roots and trying to watch TNG myself and I'm really enjoying it! I'd like to watch the entire franchise if I can, I'm borrowing it bits at a time from my library.

As for the reboot movies? Eh, I like them, they're flashy and fast - but Beyond definitely makes up for the first two's faults imo (it gave us Jaylah ♥)
