For sure, the iPhone is going to age better due to it having more powerful hardware and longer suloftware updates. If I know I’m going to keep my phone for more than 3 years, then I’d pick the iPhone.
Speaking from experience here. I know people who are still using iPhone 6S Pluses from 8 years ago.
I’m using an SE 3 as my primary. Bought it as a stepping stone, to see if I’m actually ready to move back to iOS. When I eventually save up one, I’ll buy the latest Pro iPhone.
