I think the best UI on android platform is of Samsung one UI with enhanced features. After all Samsung provides 2 year android updates to even phones under 10k, the best thing about one UI.
I also agree with you since I have one of the entry level samsung devices but the support from samsung was tremendous! they have optimized the OneUI for each device to get the best out of it! Also not to forget these awesome and useful features too! Sure.. there are some things still to be fine tuned but as an overall design.. it's so good! Personally I am a Pixel fan for the vanilla android experience but still can't forget this amazing OneUI from Samsung.
