Please expand on how it is worse. What is the BG3 equivalent of Arkanis Gath for example? Why didn't the tieflings in BG3 throw my evil character a party after she murdered them, the way the elves in BG2 do after you kill them in Suldanesslar?
I'm not sure I want to get into this game since we're digressing, but if you are talking about reactivity, I think even though it's 20 years old, bg2 is still better. It is more limited, but the story is more cohesive for it.
