I don't think you are missing too much anymore. Definitely can't say that Spotify is leaps and bounds ahead. Apple Music added a discovery channel recently too. With Apple Music you also get spatial audio and loseless audio included at no added cost. Spotify has been talking about loseless for years but don't think they've implemented that yet. Also, in the recent past Apple Music paid artists more per listen than Spotify.

Spotify is leaps and bounds ahead, feels curated but idk really. They have discover weekly which I have been able to find really great artists on. Been using them for over a decade and it hasn’t disappointed me.

Pandora is also good too a friend of mine had this for a bit and I was able to test it. You should get Spotify so I can follow what you listen to. One of my fav things to do is look at what everyone else is listening to. 😎

Might depend on what you listen to? I’ve only used Spotify
