[Open Discussion] iPhone vs Android: Which do you use and why?

I've always used Android (or Nokia previously) but this has predominantly been down to cost. Step daughter has mostly had iPhones as her dad swears by them. I get the longevity argument of iPhones, but step daughter has had more iPhones in the same time as my last two phones - but this could be down to her desire to continually upgrade and my happiness with what I have.
I've now got a Samsung A70 which is just over 3.5 years old - it feels like new. I got it for a very good price after a cashback offer and a trade-in offer (About £210). I do suspect that as Android phones can often be quite cheap - decent phones for just under £100 and upwards, comparing budget Android phones to iPhones isn't a fair comparison.
