Eh I have one of the weapons off Venekor, Ancient Sarnak War Cutlass (same DR, damage, and delay as Ancient Vorpal Blade), but I'd probably still take a Shadow Axe. Not having a proc on the weapon really has a way of lowering dps, and no tempers can really make up for the weapon not having a proc.
Though I would agree it's probably easier to dps using dw, I personally keep my 1h setup cause I tank a lot of heroic content, and the lunge reversal helps me hold aggro better on multiple mobs
