Let me explain thoroughly then. It usually depends on the situation, encounter etc.
Heroic strike +damage/(and threat) is applied more often for quicker weapons assuming you have the rage to make it happen, in low rage situations (and you still somehow have max threat) max range might be better for raid dps since revenge hits for more, white dps will be higher (the amount of 1.3/1.4 weapons are limited around 45-52dps), and incl whatever other buttons youd use that use weapon damage. In the unlimited rage scenario, the fastest weapon is the best, especially if the slower weapon makes you lose heroic strikes (as in too slow to dump rage).
