The Aguila (means Eagle) that I've bought is marked "Eley Prime". My guess is that Eley makes the primed brass and sells it to the Mexicans.
I haven't done any definitive testing, but it seems to hold its own at the price point. I heard from a major seller of competition supplies that they consider it very good. More to the point, it's been more available around here than US brands, especially CCI which I prefer.
