And why does it matter? Who has a choice which search engine they get the most traffic from? You either know a lot about SEO or get lucky and get a lot of traffic from Google or you get traffic from MSN and Yahoo, both of which are easy to get listed in, but don't convert as well.

SE traffic is all good and you should try to get it from all the major search engines. Don't worry about which one is better, it's all good.
