Re: At least it's not BING
I've found the difference to be marginal personally. Image and video search I find is far superior on Bing, WHILST Google is slight better at Web / text searching.
Working in a team of geeks, I actually opt for Bing just because everyone else uses Google. A little difference isn't a bad thing.
Certainly Bing isn't terrible, to the point if you changes the styling and branding I doubt the majority would even notice.
