Is double alpha academy legit?

FWIW, 9mm dies have advanced a bit recently. I would not consider the Dillons a good choice at this point with their small ring.
 
IIRC, the Dillon 9mm uses a ring, and not a tapered sleeve, which is fine for straight walled cases, but it oversizes the body of the 9mm leading to that weird wasp waist shape. The best 9mm sizing die I have seen is the new Lyman Pro series. Gives SAAMI dimension sizing vs the wasp waist.
