For me, it's a few things:

1. I've never been particularly fond of the ux and closed garden nature of iOS. The irony of course is that my primary laptop is a macbook, and my workstation OS is Windows and Linux.
2. I'm pretty specifically fond of the experience I get with Google's pixel line, in that I can remove pretty much all the crap wear that I can't get rid of on things like Samsung phones, they are fairly sturdy and performant, and I just like how stuff works.
