The most recent one is, of course, Sync for Lemmy. It may just be muscle memory at this point, but I find the experience a step improvement in browsing.
On my home server front, I would mention Plex despite Jellyfin's massive improvements over the past 2 years. Plexamp is just a magical piece of software.
For the most part, though, I think I'd reverse the question. Most of the time, I prefer OSS.
Try reiverr, its a jellyfin ui made by a lemmy user that integrates with the arr suite and tvmd so you can easily find new things to watch https://github.com/aleksilassila/reiverr
I agree about Plex. But I don't get the love for Sync.
It feels kind of clunky and it lacks some features many of the other apps have. Personally, I'm liking Thunder right now, but I'm excited for Boost to come out.
Sync has ads unless you pay, it's not open source, and I haven't actually found anything superior about it.
It's missing some of the gesture customization others have. I particularly like the left AND right swipe gestures in Thunder. Plus, there are more actions you can assign to them.
Thunder also has more visual adjustments. Things like edge to edge images and post action customizations.
Also, the reply window makes formatting and quoting easier.
The feature different isn't big though, and most of them aren't a big deal.
I'm not sure why you think Thunder is ugly though. The way I have them setup, they look almost exactly the same, except I have nested comments in factors more visible on Thunder, which makes it a bit easier to track the conversation.
I was unable to get the font sizes right, to change only the base font to affect all proportions, and to colorize the indented comments the way I like them. Maybe I just wasn't able to find the settings, though.
So i bought plex pass a while ago and i keep hearing about plexamp, I dont really understand why is it considered so good, could you elaborate on why you like it? Does it do more than play music from my home server?
I love Jellyfin and mainly use it and recommend it where possible these days, but man, the download situation sucks. Hate having to download files without compressing them, especially since I keep my media lossless. Its the main reason I've still kept Plex running on my server. Also sometimes the clients can be wonky, I've found Jellyfin works best for me with Kodi as the player for most things, which is interesting. But overall I do like Jellyfin and support it and its mission, hopefully gets better in these aspects in time.
