Alright, I applied some Google-fu to find out how FF4 RC1 scores on the same tests that Engadget mentioned in the IE9 article. FF4 RC1 scores 97/100 on the Acid3 test, IE9 scores 95/100. We don't need to go into the accuracy of the rendering, they both fail. It would be nice if they caught up, Apple has been shipping an Acid3 compliant browser for 21 months already. Then there's SunSpider, the results of which differ as different hardware is used, but in all the reports that I found, IE9 scores better than FF4 RC1. And lastly, there's Peacekeeper. FF4 RC1 is dead last in that test, by quite a long ways. So it didn't really matter whether Engadget used FF 3.6 or FF4 in their tests.
