Is Apple Music better than pandora? And the if so what makes it better

I like it better.

I can download and play across any of my devices and different platforms with ease. I'm not reliant on any one device to play my music. I can sign in & play anywhere.

Lots I could say about why I decided to subscribe to Apple music when I've never subscribed to any others, but the set up of it, it being extremely user friendly, and access to loads of music anytime, online and offline, are a few of the many reasons I remain.

It also doesn't take up the storage that other apps do, since it syncs with iCloud music library....

But, this is my personal thoughts. I'd try both & see what you feel best suits you ~
