Thanks for the responses.
I wouldn't say I am overly deep into any ecosystem. I have a Windows 10 laptop which can access any of the services. My new television is Android based so I can use Google Play but not Apple. However, this isn't really a big deal as if I am listening to music at home I generally do it through my Bluetooth headphones. I have been using Apple Music for no reason other than I am using an iPhone 7 so I figure why not. It integrates so well and one thing Apple Music does that no other does is sync the playlist information to my navigation display. If I use other services, it says the current song but the playlist itself says PLAY MUSIC 01 and so on. This is because I don't use Bluetooth - I plug into the lightning port and my Acura TSX recognizes it as an iPod. It sounds better doing this than using Bluetooth and it also keeps my device charged.
So based on that, I am likely sticking with Apple Music. But I was curious to see if anyone here whom has used both, or even another such as Spotify, had major reasons I didn't know about as to why they chose a different application.
