From what I read, because I jumped ship early, Robinsons run is in continuity with Rucka's, not Azzarello's. Diana being a daughter of Zeus and having a brother do not contradict anything in the Rucka run. Rucka just did not want to focus in that stuff. Orlando's did not reference anything in the Azzarello run from what I remember, it primarily used stuff from the Bronze age and Perez.
Overall Rebirth has been one of the more consistent era's, even in the low points.
