The first problem I find with Bing is the UI. You really need to work hard to see the results from ads and stupid suggestions. This is a major destruction for the users.
The second is that slow to index. Boy it take months to index new fresh and original content and data, images and whole shebang. As this data could very much help the user, but the time Bing indexed it, it's probably too late or useless.
I tried to SEO for bing, but spammers always out ranked me for competitive terms. It happens with G, but they get wiped very quickly.
I think the main core difference between Google and Bing are that the first was built to solve the ongoing problem of search, then it was monetized, big time while looking after the user experience. Bing was built to make money G makes and so far I didn't see it stand out or come up with anything new that could convert good number of users.
Saying that search engine can pick a quality document based on content is a lot of crap. Even thin content is defined by who you talk to. Some simple images on the web could be considered thin content, but they are valuable to many users. Again, spammers can abuse those.
The problem of search continues. For now, G owns the lion share.
