I've used both Spotify premium (for 3 years) then switched to Apple Music to try it, keep it for a couple of months, back to Spotify premium, then finally back to Apple Music.
In my opinion Spotify has better suggestions, but it may be because I used it for longer, but I hate the app and if your privacy conscious it's a nightmare.
Apple Music has a superior audio quality in the base plan, if you are on an Apple system it's worth the price for its integration and at least your not selling your data to others as much as spotify.
I think both web interfaces works really well anyway, if you don't like the apps
