D claws without 99 str and potting have nowhere near the k0 potential as AGS. While practically speaking your sure to do more damage per spec with D claws than the average spec for AGS.
Claws have serious k0 potential as well dont get me wrong, but the person is left time to eat up between the 1st set of 2 hits per spec, but if your up against those kind of people and things like that, consider AGS because if you hit 60+ on your first and second spec, the chance of anyone surviving that is pretty much 0.
