Qobuz's audio quality is a game changer. I had some technical issues with it with glitches short pauses in playback awhile back when I tried it; hopefully those are worked out now. It's great if you know exactly what you want to listen too. It's well known for lacking good algorithms for music discovery. I use Tidal and really like the daily discovery feature, automated Playlists, and the "track radio" that will give you a large list of songs similar to the exact song you are listening to. I've heard similar laments from people looking to switch from Spotify to Qobuz.

The only deal-breaker for me was that the android app doesn't persist its play state, so if I pause and do other stuff on my phone, it usually loses its place.

The number one thing I've been missing are Spotify jams. Spotify also has a wider selection of music, but tbh it's rare for Spotify to have something that Qobuz doesn't. Spotify also has lyrics, playlist folders, and audiobooks; though tbh I haven't checked to see if Qobuz has the latter.

I mean, Spotify is a publicly traded Swedish company.. but it is worth noting that Qobuz is French and that the original creators still seem to retain both control and ownership

Spotify Connect is a feature I use extensively that nobody else even comes close to doing as well (even though the Spotify implementation leaves much to be desired). Why does nobody else support controlling the player on my PC from another computer?

One example is podcasts. I would miss the single interface for both podcasts and music, although Spotify is enshittifying rapidly; the turning point may be closer than I thought.
