I would much rather use google, I don't like the navigating on the bing website, i really don't like the overall style of bing, i will always choose google.
We are very early to compare bing and google.i think we must have to wait for bing. it is new so cant make comparison with google.
I also get way more hits from google, but if you compare it to the approximated total number of users, bing seems to be slightly better to me. It looks like bing is ranking new sites higher than Google does.
