Having tried Apple Music, Deezer, Spotify, Amazon, Tidal, Soundcloud, and Qobuz, I can tell you that Apple Music doesn't have the best UI or features. It's a nice service, don't get me wrong. Top 3 for sure.

Also, the ratings on the Play Store aren't the best indicator of a great app. On the front page of Apple Music there's a 5 star review saying how Chromecast doesn't work. Which is why I prefer to just try all the apps myself.
