I don't know what vanilla has, you'll have to compare the patch applied.
About the new AQ, i think you refers to the
TriAQ patch, wich add aq2 and aq3 mode. The original author of this patch made it most for anime purpose. Even if nothing prevent you to use them on something else than anime, for the few i've understood from aq3 mode, its purpose is mostly for anime "kind" video.
After, aq2 mode may be a more generic use.
Unfortunately, there was almost no information on this patch...
But my real advise would be to try.
