Hmm... I find barbarians are superior for pure tanking, but less useful for ranged combat. They can use thrown weapons well enough, but thrown weapons have no range. Thus, use a barbarian with dash to tank, and the fighter to pick off the other enemies.
Half the time, my HO barbarian went in alone and killed everything. At levels 1-5, use Houndstooth collar, than go for 2handed weapons to REALLY deal damage. Barbarians are better at running in and killing, but a fighter is better for 'smart' fighting, like ranged combat and using lots of feats rather than Barbarian rage.
