Plex is still good, I've been running it for a decade. It was incredible when I started using it and they've added improvements I wanted in that time. I'm not too arsed about some of the recent additions, but I've never not been able to disable something that I didn't want
Jellyfin is good too, and I'd probably pick it if I was starting a new server today, but I've yet to actually experience anything negative from Plex, and still feel like I got value for money.
Possibly big caveat: I got a lifetime Plex pass ages ago, I've not paid attention to what they're charging in a long time.
