I don't think search result quality is on a linear scale so it's hard to define "better".
The results will definitely be less personalized, which will be a big plus for some people, and a blocker for others. There will be a few other dimensions where we can stand out, and some where we will have a hard time catching up (index size for instance).
In the end, given enough contributors, I'm pretty sure the results can get "good enough" for most people, and hopefully "better" for some ;)
