I migrated from Plex to Jellyfin maybe a year and a half ago and haven't looked back. Great user experience and works so well out of the box IMO. Good Android app, too. Works with Chromecast, too (though I've been trying to ditch Chromecast in favor of just a laptop connected to the TV via HDMI).

I started digitizing old home movies that were on VHS and created a "Home Movies" library for my family; none of us had watched them in ages since none of us have a VCR anymore, lol. Great mother's/father's day gift for one's parent if you've got the time and equipment. It's nice having the whole family able to easily stream our home movies.
