Let me say these are different games that will bring you a completely different experience. This is one of the reasons why I don't understand why people compare them here. It's the same with Pathfinder, which is a very difficult game. I will not play Solasta, I have never been interested in the gameplay in such games, I play similar isometric RPGs for story, so I will play Pathfinder, although I do not like its complex gameplay. BG3 is my favorite, because it combines a story and a simplified (convenient for me) gameplay.

As a result, each game will give you a different experience.

I don't speak english well, but I try my best. Ty
