As much as I liked Divinity 2 DKS, if I had to pick which I liked better, it would have to be Divine Divinity.
For me DD wins over DKS because it was much more a complete world simulation. Go anywhere, anytime (except for the endgame location) as long as you can kill enemies you can go there. There was day/night. Like the OP stated, there were other creatures interacting with each other in various ways.
I was hoping that DKS would retain these features and since it didn't it somewhat detracted from the game.
