Both (or all three) are roughly as bad the others so it really makes no difference. And as far as I know Bing is making tiny increases in market share at mouth-watering cost.
I do note though that the Yahoo share is staying roughly the same which shows that the average user can't distinguish between Yahoo, Bing and Google. They are just sticking with the same old search engine they always have.
