Can't speak to current production but 10 years ago, Aguila Subsonic ( in the Purple box) was one of the most used ammo in our regional Gallery (bullseye) league. It was reported to be made in Mexico on Eley equipment and using Eley primers back then. Irregardless , as long as your gun would run it, it was by far the best bang for your buck in target grade ammo. It was somewhat funny actually, as you'd see lines of top ranked shooters running $1500 European target pistols with (then) $13 /brick ammo. I remember placing one order for 30,000 rounds of the stuff. It was that good.
I don't shoot competitively anymore but still hoard treasured bricks of the stuff to feed my Pardini SP.
All that said, the two gripes many had was:
1) Aguila (all flavors) had a waxy coating that would gum up your action quicker if not wiped off prior to mag loading.
2) The subsonic in particular had the best reputation for accuracy but , due to its lower power, would not run reliably in some of the US made Ruger and S&W target pistols without mods..
