If you have blitz, first blitz than go for d claws. I would recommend d claws as they are cheaper + ags is slow they can protect from melee before 2nd spec way faster.
In my experiences, I've had trouble with claws alot at the pure level because too many people have pnecks... s0z bud but either way you're gonna get trouble (inconsistent ags vs. pnecked claws)
