Self Priming Aura paint vs Priming Then Painting
We were in the same situation as you last year. Benjamin Moore recommended that we use a sealing latex primer first on the new drywall and then use the Aura pain. It worked out really nicely for our walls.

As an aside, primer is a fraction of the cost of Aura paint. So if you have to do do 1 coat primer + 2 coats Aura versus 3 coats of Aura, the primer + Aura will be cheaper.
