I've been using Google Fi as a wireless provider for years and have been using their phones as a result. I've only once ever had an issue with one of the phones from a software standpoint and it took me a while to figure out how to port over my contacts (I had to export them to an Apple format and then import them). I've stayed away from Apple products because (1) the Google products don't have a ton of corporate fluff like Samsung products, (2) Apple phones tend to do "magic" things that just annoy the hell out of me, and (3) Android Auto just works.
