Yes, AQ test is definitely more scientific, IMO. The Aspie quiz is based upon a theory that the autistic mind is more in tune with our caveman ancestors (or something along those lines)--a theory that has yet to be proven. The AQ is a good scientific test. While not designed to give a diagnosis, it will give you some sort of idea. (That being said, there are people on the spectrum who do score lower than 32, and some not on the spectrum who score above it....but it is still a good foundation to use). When I participated in an autism-related study, I was asked to take the AQ test there. This was in the psychology department of a university campus, so scientifically they do see value in that test.
The AQ test also seems to be somewhat based upon a particular hypothesis, namely the hypersystemizing/"extreme male brain" hypothesis (which I consider to be flawed - to me, it appears that hypersystemizing is not the underlying cause of autism, but the result of something else, since there are some autistics who couldn't really be considered hypersystemizers).
