Well, 5 Base D on DRK is like 5.00%~ DoT damage and ~3.57% on WS.
12 less delay is a 2.40% DoT and WS frequency advantage for Perdu, and 14 Attack is hard to quantify due to level correction but typically in the region of ~3-3.5% DoT/WS damage.
Perdu should win on both counts here. Only when hyperbuffed will Death+1 win (the Attack has to be severely diminished).
Note if the Death+1 uses Sword Strap and retains 6hit (which it can), the difference from the Pole Grip is still enough to keep Perdu in the lead.

Death HQ is only 2.4% ish.
