Do you play mostly low level (1-5)?
Barbarians at low level deal tripple or more of most other PC's damage and with their HP can roll through most opponents. But at higher level the barbarian get's easily outdamaged by arcane casters, has a craptacular AC, is inflexible and all the hitpoints in the World won't help him against a dragons or giants full attack.
Exactly the point I was going to make. They tend to be quite good at lower levels when ACs all around tend to be low and HP are low as well. In later levels barbarians tend to take horrific damage because of their low AC. Once the fighter gets enough money for better gear, the AC difference can reach a 12-point shift easily.
Good Barbarian AC: 10 + 10 armor (Brestplate +5), +3 Dex, -2 rage, +5 deflection (Ring +5) = 26
Good fighter AC: 10 + 13 armor (Full Plate +5), +9 shield (Tower Shield +5), +1 Dex, Ring +5 = 38
Of course the barbarian is probably using a Greatsword or Greataxe and the fighter is using a Bastard Sword 1 handed (because he can spare the feat). That AC difference at higher levels is translates into up to +24 damage per hit from a power-attacking giant using a 2 handed weapon.
The extra damage the barbarian can inflict gets counterbalanced rather severely by the beating he tends to take from other heavy melee types. Mithril plate mail tends to help a bit with 3 extra points of AC, but that is still woefuly short of the fighter who can use Adamantine platemail and get a DR 3/- to further cut down on his damage.
Most barbarians don't use shields simply because you loose some of the biggest benefit the barbarian has (the bonus Str) unless you use a 2 hander for 1+1/2 str. Of course the fighter will dish out less damage in sword-and-board mode as well, but he will be far more survivable in the land of hard-hitting, high BAB opponents.
