My personal results are that you can totally ditch Google Search, Gmail, etc, and no, Google stuff is not orders of magnitude better. Nowadays, living outside the GFW again, I switch freely between Bing and DuckDuckGo, but it will always be a pain in the ass not having access to Youtube. That, imho, is Google's killer product.
And then you have things like Yandex which is a tad better than Google in Russia and Baidu which does the same in China (compared to Google HK)
