I bought an AQ2 kit as a spare kit to trash around and was so blown away by the sound of it, I decided to buy more parts for it to be able to mix and match into 2 small kits or a larger kit for prog duties.
I have no complains about the AQ2 series for the price, however, it doesn't get 5 stars as the hardware is not as solid/dense/high quality as I'd like.
But then again, brilliant for the price.
IMO the shells compete with the Mapex saturn shells line (although they are not hybrid), and the hardware kinda competes with the Mapex Mars lines.
