You can’t say jellyfin is far ahead of plex when it doesn’t have nearly as many clients as plex does. I’ll agree that in the free tier jellyfin is better, but as of now it’s not as fully featured as plex pro. Even non pro plex just makes it easier to share outside your home too.
Hmm looks like they have a WebOS client now. Personally that covers my personal use case since the family that I share plex with just has rokus and apple tv
