Right now I think WotR is the better game with the better main story.
+1. This is basically my opinion. If I could somehow transplant WotR's main storyline (and combat system) into BG3, the latter might have a chance at 10/10 status. As it is, I like this game, I'm sure I'll replay it off and on over the years, but (like PoE2) I just don't enjoy the main plot, which is a fatal flaw for me.
