Depending on your toon setup this ability can vastly outperform greater whirlwind, a toon with a natural 5 apr, which can be achieved many ways as a dualwielder, adds in an improved haste spell to double that to 10 apr for its duration and critical strike making every attack a natural 20, which is first a guaranteed hit, then on top of that a crit, leaves greater whirlwind in the dust damage wise. Where greater whirlwind excels is for toons with a lower apr such as 2h or ranged weapon users, but even then it is often stronger against enemies that have a low ac simply because it will always be a  hit rather than a roll of the dice.
