If you ask as romance, I'm an Aerie fan
I think she's very blunt but she's useful. She is multi-classed but she gains levels very fast 'til level 13 because she's druid. She's got useful spells. Also with a gaunlets of ogre power she can be useful in combat. My party is Me,Minsc,Aerie,Nalia,Anomen,Jan. I like to restart after I beat the game with a totaly different party except Anomen; Me,Keldorn,Valygar,Jaheria,Anomen,Yoshimo (Imoen) Jaheira is cool specially her insect plague spell but I wont replace my Anomen with her
