Dual Blades (Twinblades) are the assassin's choice: fast flurries, aggressive movement and one of the highest DPS ceilings in the game. Infernal Twinblades is A-tier in PvE and S-tier in PvP.
The trade-off is difficulty — you're in melee range constantly, so it punishes sloppy parries. Strong once mastered, but not a recommended first weapon.
