Just because you can get a combo up high doesn't mean an increase in DPS enough to lower the attack of the wep. The aran booster is also better than other booster because it raises the speed by (3)...? so the speed of a pole arm will mean less. Also, the speed between attacks while using double/triple swing is the same no matter what speed on the pole arm. Not sure if I can confirm that but me and a friend spent about 10 mins trying to count how high we can get our combo within a speed limit while using a Surfboard compared to a steel polearm (both with lvl 16 booster). It almost always came out to be nearly the same number.
