Before getting my Apple subscription, they would let you search their catalog, play some songs, and sample the others. All services are being competitive in getting a huge catalog now.

The main advantage I noticed with it is more albums coming out in Atmos: some sound good in surround, some are too artificially moving instruments all around. So as far as services, I have Apple because it's cheaper with my cell plan. Switching between the same song with one service and the other might still sound different if you're listening to one on a web browser (and its audio player) vs an app and its settings. Though I would say the Mac is a little less intuitive if you're needing to get into more advanced device settings (instead of going to sound settings, to go to Audio MIDI Setup app). I think all OSes are also similar with your perceived sound quality is more dependent on the audio driver settings. I've never had issues with Apple formats through iTunes on Windows machines. I'm computer agnostic: I have a Mac, Linux machine, and 3 Windows 11 machines. The only main difference I hear with sources with my speakers is what level the levels are set for speaker channels and subwoofer (and most times comparing a digital streaming movie with my UHD disc is the lossless disc has higher levels).

I'll listen to music over my main speaker system through Apple TV (or Airplay to my devices from my iPhone). Not sure if all they're doing with lossless is going to a previous master and using a different compression codec, or indeed doing a new mix. I've noticed they have a lot of albums now that are lossless and more being released in Atmos 3D surround. I have an Apple Music subscription through my phone provider.
