I'm actually somewhat of a fan of this ride in spite of its flaws, and the AA's are a part of that reason. I'm mostly on board with Disney's dino AA's being better than most of JP's dinos, again with the exception of Japan's t rex.
I would assume compliance is the reason Disney's AA's have a more fluid motion to them, something they apparently have a patent on. It does add some realism to human and other animal figures, though Universal has made some truly awesome figures without the tech (such as Gringott's goblins) and I would still praise them even against some of Disney's best. Though compliance is still great and certainly does tend to improve AA's noticeably.
HOWEVER, and i'm surprised to be saying this, I don't think the lack of compliance is as much of a hindrance to reptile-based AA's including dinosaurs. That's not to say the JP AA's in Orlando don't need work (they could use some improvements, even disregarding compliance), but the absence of super-fluid motion (seen in Disney's human figures) isn't really as big of a problem for reptiles. Reptiles in actual life tend to have very jerky almost mechanical movement to the naked eye (many birds do as well). Anyone familiar with Florida will probably notice the masses of brown (and occasionally green) anole lizards we've got skittering around. They have extremely odd movement, standing completely still and making sudden jerking motions with their heads or bodies, able to move so fast and precisely that it can seem instantaneous unless you're looking closely.
