If you seriously believe Bing is better, then go for it.
If you think Bing is better because they show your site better, you'd probably do well to stick with Google.
As for me, I'll stick with Google - proudly - until Bing is REALLY better :)
As for how my sites appear on Bing, compared with Google? Never looked. And probably won't until I've had at least ten Bing searches that were more useful than Google.
2 years? probably :)
