Give it a try.

I was a Plex early adopter. Left Plex for Jellyfin when the Jellyfin project was barely a year old because it was clear where Plex was heading. (Emby was another option then, but they made some decisions I couldn’t abide so I skipped right over them)

0 regrets, and even my non-technical spouse and two children have no problem with it.

Everyone’s got their opinions, but the one guy slagging off Jellyfin below sounds like he’s never actually used it.
