I'm using Symfonium. Originally got it because it allows pulling from subsonic, plex and jellyfin libraries simultaneously.
After switching all my stuff over to navidrome, rather than having it split between plex and navidrome, I kept it because I paid a couple bucks for it and really like the customizability
On my PC I use sonixd. No particular reason for that one except it was probably the first one I found, is cross platform and also looks quite good
substreamer on android, and feishin on windows
Over the last few days I've tested substreamer, DSub, Symfonium, Ultrasonic and Tempo. I thought that Symfonium was the clear winner (once I'd found the setting to use a local cache) with DSub being next. I wanted to be able to browse albums by genre - others might not care and rate them differently.
Symfonium is closed source and not free, which might be a deal-breaker for some, but it's a small one-off payment to an indie dev which is A-OK with me. Turns out it's the same dev that wrote Yatse (xbmc/kodi remote) which I'd also paid for.
edit: Ah, the other comments hadn't federated - I see I'm in good company!
I've been using dsub but it has a lot of weird bugs (I might try to fix someday). Testing symphonium now and it seems pretty nice so far. Thanks for the recommendation!
On macOS I use SuperSonic. Sadly, there's nothing I really love on iOS. Substreamer and play:Sub are probably the best.
Substreamer on iOS, I've been getting surprising amounts of mileage out of the "play random song from your library" feature recently.
That's a feature that I have also come to like again, recently. Oftentimes when I add music to my library, I don't listen to all of the songs immediately, this way I definitely learn about new music that I already own...
I like symfonium. It's so polished.
Dsub, because It's very stable with just enough features and a usable UI. Ultrasonic is close, but there's a glitch I'll have occasionally that causes my music to play twice. Haven't checked to see if it's been fixed in a while. Substreamer is very pretty. Last time I checked, it was missing gapless playback. Synphonium has a weird tendency towards offline. I believe playlists wouldn't update right. But the main reason I don't use it is that it's the only paid app, and I'll occasionally not have the Google Play Store.
Finamp is very nice. I use symfonium because it is the best app for the task. It auto caches whatever you want, e.g. all 4/5 star songs. The UI is very nice and customizable. The auto playlists are very nice
On pc I use strawberry or the webplayer
I use Ultrasonic.
