None of them actually sell your data, and both of them have personnalised ads. The difference being one pretends to be a privacy warrior and the other has pretty detailed and granular privacy settings (spoiler, that's not apple). Dont get me wrong, I dont like Google either and they probably collect and actually process personnal data than apple, but both of them are absolutely terrible and both of them absolutely know everything about you. It's just that apple is much better at preserving a good brand image. Though one valid point I could see is that having a phone made by apple reduces the likely number of parties who have access to that data, on android, you often buy a phone from samsung or the others, and then they also have their spyware on theere
