My thoughts:

Apple Music is so much more baked into the Apple ecosystem, isn’t a rip off (as I might expect), and doesn’t have crappy selection (as I was afraid of — it has pretty much all of the niche stuff I didn’t expect it to).

iCloud and Apple Music are just part of the device purchase for me tbh. The whole thing is supposed to work together, and it does for the most part.

Someone mentioned regional licensing issues on Apple Music, which makes sense. I have not seen that yet in the US.
