Weird that you find them comparable. I've compared the two and Bing's results are just kind of weird (old results and non-related results come up). It's worth 50 cents a day for me to have decent results.
When did you do the comparison? In the summer of '09 when Bing launched I gave it a shot, but just did not like it as much as Google. A few months ago I went back and tried it again, and have not gone back to Google since.
