Personally I don't think there's any doubt that Google's search quality has fallen down over the last few years.
There have been a few instances where what I was looking for was not found on Google and I gave up looking for it. Later (after a few months!) when by chance I tried the same query on Bing, the results showed up right on the first page. Surprised by this, I rechecked it on Google and it appears either on the 3rd or 4th page - something I would never check earlier.
Since then I started always doing a backup search on Bing for anything important, to see results I might have missed on Google. By now, I'm using them 50:50.
Also attended a lecture on Bing search, and learnt that their approach is a little different, which could acount for this observation.
