Google not only says the webmasters to provide the best user experience, but also follows the same principle, I believe. Quality is the single factor that determines the fate of a site and also for a search engine. Google is not an exception. It is 100% true that Panda is all about quality. You says that big brands are not affected by Panda. But the best example is Hubpages. Google has to give more important to quality( it really does ) to remian at the top.

One of the recent updates is about the travel information that reminds me about the hot topic not long ago about Bing giving more accurate information about air travel than Google. It shows that Google is not complacent about its current position.
