I don’t think you’re being objective here

I don't feel that's the case. I feel that you're the one not being objective here. You're holding things against Jellyfin which have nothing to do with it as a platform, but instead are either misconfigurations on your part, or involve your local setup...

I also run both. I don't see what this has to do with anything. I'm not lambasting you for "choosing" Plex over Jellyfin. I'm saying you're not being objective while pretending that you are, which is simply objectively untrue.

I use Jellyfin on my devices, except on Android TV because the app is painful to navigate.

Again, this is you not being objective. You personally don't like the way the Android TV application is laid out (which is totally fine) and count that as a negative against Jellyfin--which is my issue. Objectively the Android TV design follows the current design schema for TV applications and is the same layout as most media platform applications for Android TV...

Plex is way better for sharing

Which is not what these applications are designed to do...so it's not at all weird that this is the case. You're inventing shit up as metrics to compare Jellyfin and Plex and it's just so incredibly weird to do.

These are both media streaming platforms, which they both do relatively well. The main issue between the two is Jellyfin is FOSS and Plex is not. Plex incorporates a ton of proprietary bullshit that you have to wade through or disable to get a similar experience to Jellyfin. Like "shareability." That's not what these platforms are designed for. That's what Plex was changed to provide. Comparing Jellyfin and Plex on the basis of "shareability" is like comparing a Ford Pinto to a Ford F-150 and comparing their towing capacity. It makes no goddamn sense because the Pinto was never designed to tow anything...
