Samsung OneUI has good UI and performance, but the 3-year support limit is terrible and unacceptable. I own various Samsung devices, their policy of abandoning 'old' products to bit rot or quietly making them disappear from SmartThings with an update convinced me that they are not as dedicated to their products as Apple is. Today's phone OSes aren't "just" OSes but whole ecosystems of devices. When I buy TV or smartwatch I expect that it won't become e-junk in 3/4 years. The rate of change is currently so slow, that new devices don't bring any new features that are forcing for the upgrade. They are just a refresh.
