I have a Pixel 3a and longevity of phone is important. But Android is cutting down their supported cycles to 3 years. Unless something changes, in fall next year I will get an iPhone 14/15 (possibly refurbished) and keep it for 6/7 years. ios16 is still possible on the iPhone8 - a solid 6+ years of official updates!

Walled garden or not, their products are solid and supported. That is what most consumers look at. No hassle ownership for most.
