When talking about UI it is important to differentiate between functionality and looks.
From functionality standpoint Solasta's UI leaves BG3 in the dust. It's grouped in a way that you will use your abilities. It is eather imideatly obvious where the button you need is, or you can easily gess, based on type of action it represents. And it is obviouse what type of resources it will cost.
Looks are subjective. And much easie to adgust. So I don't think that it requires much discussion.
