They do have 2 HP, and better hand to hand combat rating. They can hide anywhere I believe and make excellent flanking units, and have slightly better stats if I am not mistaken.
I do find that more arrows is better, so they arent as good as retinue longbows in most situations. But they do well in the forests around wherever they are recruited from, and also as a wall unit as Kadagar_AV pointed out. Not for going on campaigns with, therefore, defensive.
