Several years ago I bought a Samsung Galaxy S8, 1 year after it was released. It received a full OS update then and 1 the year after. Beyond that, there were no further updates. In 2021 I bought an iPhone 12 about 6 months after release and, can still expect a full OS update this year and maybe next, plus security updates for another 2 years. If, as I do, you use your phone for banking and contactless payments, that kind of thing is important.
And, another big plus, I'm not being followed around by Google and their incessant attempts to spam with advertising. Not having an Android phone, means I can go through life without ever logging-in to any Google services.
