Adding my anecdote: I bought an iPhone X used in 2019, after being an Android user for a decade. It replaced a Pixel XL that I had for a couple of years (received new as a warranty exchange for a faulty Nexus 6P), but which was already going out of security updates. I had the battery of my iPhone X replaced at an Apple store a couple of months ago, restoring it to essentially as-new condition. And given Apple's track record of OS updates, I expect it to be supported for some time to come. That combination of first-party repair options and long OS update support gives iOS the edge over just about every Android manufacturer, IME.
