I tested getting off spotify last year, but the other apps were so bare bones and featureless. I tried most of the popular ones, Quboz, Tidal, Spotify, Apple music, youtube music, amazon music.. i think 1-2 others. Thankfully there's an app called soundiiz that for like $2-3 will sync all of your music app playlists/favs/etc to one another.
ALL of them had absolutely useless/bad Android Auto/Carplay apps. I know at least half of them (quboz tidal for sure) didn't have a way to search in the car app. Quboz or Tidal didn't even display your subscribed albums/playlists. I forget exactly but I think I could only play their recommended stuff. Exacts are off here but I remember specifically sitting in my car with both of those apps wondering why I couldn't figure how to play my fav playlist or search for an artist.
Then the social stuff. I share collab playlists with a few friends. Apples adding these feautures IIRC. Surely not important to most people but they really make the other apps just feel barebones. I like gamification, rewinds, badges, etc.
I haven't had many issues with Tidal's CarPlay support. I've only used it in rental cars (so cars that shipped mid to post pandemic) though.
It definitely shows subscribed albums, etc. The one exception was that, on an older Toyota, it only showed the first dozen or so albums in my collection one time out of the dozen I drove the rental. Parking the car then coming back a few hours later fixed it.

The Carplay thing is the killer for me, though.
