I've done almost everything (except most origins) because you can savescum through different choices and all the endings in a couple playthroughs. Resisting Durge was my favorite.
I agree on Astarion's origin. You lose most of his personality and it's like after the beginning of Act 1 the game itself forgets the character is a vampire. Also, the narrator sometimes says things that you want to argue with after getting to know him as a companion. Like how
the sun on his skin feels like "a caress of a lover who doesn't know better yet".
