I know the raptor has a better more durable day filter imo. I have also seen different variations in the shuttered eye guard on the aquilas some are ok, the others are like spring loaded, i wasnt a big fan. I would also venture out to say that the mount on the raptor is more robust. Ive looked through 5 different raptors and 3 different aquilas, if money wasnt an object i would go with the raptor. As a side note which the really doesnt matter as long as it performs but the aquila is fugly as shit, the raptor housing look's more tactical and sharp vs rounded contour, again my personal opinion of the two.
