Samsung user from s2. Used s2, s3, note4, s9, s21 ultra
Updates have got lot better. Not as fast as ios. But I personally feel Samsung UI is overloaded with features which makes the phone slow after one or two updates. I can pickup 6 yrs old iPhone and still can run it pretty decent but a 6 yr old Samsung will be slow and cluttered. Hardware quality is not on par with iPhones but android has best flexibility for customization. But hey, ios is getting better too. In their own way as typical apple style.
