I had a number of sites using a Flash clone which, I discovered, stopped the pages from loading in Chrome although they worked perfectly with all other browsers. Despite this all these sites had pretty good rankings in the G SERPs.
The logical part of my brain (which isn't always right) tells me that if G used Chrome for ranking they would be nowhere. Therefore they don't. QED.
