With the caveat that I rarely use any of them because I prefer having my own files, CDs, and records, I’ve gravitated towards deezer for the most part, apple music the rest of the time.
Reason being that deezer is the least annoying as regards setting up playlists, and apple is my wife’s preferred service, and it’s usually easier to just let her set up the playlists and then make suggestions for adds/removals over time lol.
Mind you, I don’t really like any of the interfaces of any of the services. They all suck in different ways.
