Factoring in a few of the other ways you didn't list, like sites with YouTube videos, we can guess Google is aware of about 85% of consumer web traffic. Using their DNS would tell them the only the hostname of the other 15%, and only once per TTL. So call that 7% from using Google's DNS.
Using anyone else's DNS gives that other company 100% of your lookups rather than the 0% they had before. 100% is a lot more than 7% or 15%, so you're giving up a lot more privacy by using any DNS other than Google.
In other words, Google already knows which sites you're visiting - you got to those sites by searching Google. Why would you also give that information to some other company?
That was my thought process after I found that Chrome is so good for web development. I'm using Chrome, so Google has a profile of my web surfing. There is no reason to let another company have the same information, so I'm better off using Google services all around. (Besides the fact that Google provides good services, which get better as they are integrated.)
