MS and google both know what porn you are looking at. What you buy from your PC etc... MS knows how much time you are spending playing games + has screenshots of all your encrypted conversations etc...

There are so few native desktop apps these days, it's all on the web.
And the browser can glean a lot more about user interaction than just web traffic, like where you hover, what parts of the page you're interacting with, etc.
That's why I said that (combined with phone), Google probably knows more.

But it's probably a pretty close competition
