1. Freedom. I should be able to build and run apps on it without the platform holder having a barrier on it.
2. Privacy. The phone shouldn't be an object to track me for better ad sales or any other purpose.
Of course, priority 1 has until recently always led to Android while priority 2 has always led to Apple.
But with the upcoming announced changes where google is going to require registration and signing for even third party sideloaded apps, while at the same time the EU is forcing Apple to open up and allow sideloading, it seems pretty clear that in the near future both Apple and Google's policies regarding point 1 are going to converge. On a position less free than Android has hitherto been, and less free than I would like, but unfortunately they are the two options on the market.
So with priority 1 no longer a differentiating factor, it comes down to priority 2.
I've used both Android and iOS over the years, as while my personal phones have always been Android, my employer provided phones have always been iOS. I think I do prefer the Android user experience and have used enough of both that that's not just a factor of which I'm accustomed to, but it's also not the huge difference it once was for a lot of apps.
Right now I'm using a Pixel 7 Pro and I might weigh sitting it out another year, but my USB-C port is failing and I'm also watching the pixel battery issues creep up the model range to newer and newer models...
