Before starting I must say I deeply love both games.
I don't quite see how both experiences are comparable since BG3 is a more cinematic presentation while WoTR is a more classic 90s. Yes, they are both CRPGs, however, what they are trying to achieve is completely different.
WoTR is focused on delivering its complex systems and grand narrative. But the effort in each scene is a big wall of text that focuses on voiceovers and scene descriptions that appeal greatly to the player's imagination.
BG3 is a cinematic experience focusing on the involved characters and developing them emotionally and in empowering situations.
I intimidated a lot of folks in WoTR, but none of those moments came close to my barbarian intimidating Kagha to release the child. We can see the fear in her eyes.
I know that liberating Drezen, and getting your powers and powers are also really epic moments, including the game's superb music. However, the focus of WoTR is on the world and how you shape it and not on personal and character development besides the role of the commander.
