Weapon damage and strength are only highly weighted for dps. They mean nothing to a tank because all they represent is threat, and threat is only a problem for a warrior if you're playing with mittens on. The difference that matters between those weapons is 4 vit and 39 more accuracy than you need (you should be reaching cap without it easily) vs 37 parry and 26 skill speed (which is a relatively weak stat, but less weak with the IB change).
