One UI, is a successor of Samsung's much enhanced Samsung's Experience Home feature. Now it's in just a beta stage but the UI looks clean by the type of other handset manufacturers. One UI is polished version of Samsung's Experience Home. Nevertheless there are some new features with keeping in mind about the one handed operations and the size of the smartphone.
Samsung is working like Microsoft now a days if we compare Windows Vista to Samsung's touchwiz and windows 7 to Samsung's Experience Home running on new age Samsung's smartphones and One UI to windows 8. I said windows 8 because they have introduced metro user interface to it and just like them samsung is also introducing the minimalistic icons to it's UI which are not needed and mostly looks like Chinese branded phones.
If samsung team is reading this, then it's my suggestion to them that please don't need to minimalise the icons as we have seen in One UI.
Apart from its visual graphics Samsung's improvise the task manager facility in view of Android Pie. Further the night or dark mode of app is also worth.
Battery optimisation is also the key aspect for which samsung improvise it's device maintenance application which is in built.
All in all One UI is polished Experience Home interface though it's too early to say as it is in beta stage. Samsung must focuse on giving regular update rather to enhance the UI only.
