I prefer dual daggers on a stamblade, I just think you get more overall bang for your buck than swords or maces with our high crit damage. However, swords will give you 5% dmg against everyone (including damage shields), so that's the usual recommendation that I see. If you gold out your daggers, they'll also be pretty viable for a vet dungeon DPS setup along with VO or maybe Viper if you don't have VO.
I also prefer a 2h maul over a 2h sword, especially if ganking - because in that situation you aren't applying major fracture during your heavy attack > incap opener and Maul gives you the full 20% penetration value.
