I see 5 results from creativecommons.org as the top in bing, but thats as an Australian. When you switch it to US, its freesound. Even as US bing shows 3 results from dvguru that appear to be spam. It also shows 3 results from creativecommons, 2 of which appear to be somewhat un-useful, and the 1 other useful one appears on both google and bing.

I'd definitely call that search a win for google. There are far more useful sources of creative commons sound effects in google's first page.
