Actually, I have liked the story of the BH so far. I made mine 100% lightside for a change (I normally so with full blue for repub and full red for empire) and it has been interesting. I shocked myself when I made the choice to make her a tank and OMG it is extremely fun. Honestly, try both through Dromund Kas and see which you like better. Both classes have excellent advanced classes that play well and their powers flow well together.
