Did you know that the level and hit points that your npc's start with are dependent on your level? If you import a fighter of 9th level instead of 7th, your npc's will have higher hit points and levels sometimes. You can get Anomen with 9th level fighter instead of 7th sometimes too.
Jaheria is better played out as a light tank, and she is a spell casters nightmare with her spells and weapons. Weapons such as the sling, spears and staffs, with a good mix of summoned monsters and a mix of offense and defense spells, plus the ability to hit things and take a few hits make her a nice choice. Weakness is that she levels slow, needs a str item (she has decent con and dex), and unless you use shadowkeeper is limited to one prof point in two-handed weapons [bulldoodoo!dangnabit].
Anomen is great as a cleric-tank! He has good str, decent AC (jaherias is better lol), and decent con and wis (once knighted), can speciallize in alot of slots and make use of war hammer, flail and mace which have some great weapons available. Bad points are his lack of dex, bad attitude (untill knighted), low wis (till knighted).
I usually use Anomen, Minsc and me (the nutty bezerker) up front, with Jan, Jaheria and Iomen in the back.
Best all time Npc? Minsc and Boo! Why? Because I like em! That's why
