From a support after the sale perspective? Yes it is.
The $399 2016 iPhone SE is still getting security updates today.
The original Google Pixel is also from 2016 but stopped getting any sort of updates at the end of 2019.
If you want a basic phone that will be supported as long as possible after the sale, the support length per dollar spent proposition of the SE models is pretty unbeatable.
I think this is a major factor that is driving market share towards iPhone.
