If your main character isn't a paladin, then you really should go for Keldorn. He's the only NPC who can use the holy avenger, which is a 2h sword that ROCKS.
Haer'Dalis is a blade, which I consider as the worst Bard class, since he's got half lore value, the one thing that makes bards special. Alright, ha has nice fighter abilities, but then, why don't take Mazzy and leave him behind?
