Care to share your moving from Apple to Android experience?

I currently have an older iPhone 6 Plus and it's really about time for a new phone but I'm going back and forth on sticking with Apple and getting something like an iPhone X OR switching to Android and getting something like a Pixel 3.

Can anyone share their experience doing that switch? Will I be able to keep my music? Is there anyway to transfer saved content in Apps over the Android versions of those apps?
