Bg3 isnt completely out yet so its hard to really judge but I absolutely adore Wrath of the righteous and would have to say, almost with certainty that I will prefer it over BG3 at this point. While Wrath has some dips in the writing and it did feel rushed towards the end, its comprehensively one of the most impressive cprgs and rpgs in gneneral I have played, my issues with it are minimal and very personal at that. Whereheas I have issues with the general approach and some major decisions that BG3 did and thats before I look at the story (which I just do not judge so far).
BG3 seems to be doing a lot of new and different things, not neccessarily to my tastes, while Wrath pretty much masters all I enjoyed in the classics of old.
