Really?
After about 9 months, you are pushed to the slow train in terms of software updates. You'll skip most of the monthly security patches, you'll get a major OS update maybe 10 months after it is released, and after approximately 2 years it's no more software updates for you.
All iOS users get the same software updates on day one as released. Devices are typically supported for 4-5 years with updates. And this helps protect the resale value of your device, should you wish to sell it on before buying a new one.
Samsung charges prices in the same ballpark as Apple but with almost none of the customer service or care.
