It used to be that android was the choice of people who had specific reasons to not get an Iphone (avoidance of walled gardens, lack of swapable batteries, demand for upgradable storage, and the like). Because iphones were generally better overall unless you needed something they did not provide.
Now, it’s neck and neck as to which phones and which OS is best. So the choice really comes down to a philosophical trade off. You can have a phone that gets updates and security patches for years and that does not spy on you and sell the data to advertisers, but is a closed walled garden when it comes to apps… or you can have a phone that is more open ecosystem wise but it may never get timely updates and it spies on you for advertising purposes.
