We engaged in a discussion in an earlier thread about claims for various polishes/waxes and scientific evals for the products ie Consumer Report style. Here is a link I found on another forum to support Zainos superiority:

I too am a Zaino user and happy to have found support for the raves. Previously used Meguiars Gold which didnt do too well in this test. Sorry if this link has been posted before.

 

Yeah, this is a fairly old site. They did this test a while ago but it is still valid!
