Not the person you originally asked, but I can share a relevant experience.
I definitely have concerns with the amount of data Google has about me and, in particular, the idea of Chrome monopolizing the browser landscape. As a result, a few months ago I tried switching to Firefox, complete with container tabs and scripts which removed Google analytics from everywhere. The difference in search results was very noticeable. Most notable was that my Google news feed (on my Android phone) and YouTube recommendations quickly became filled with generic junk, whereas before it was so relevant I would often find the answer to something I had been researching earlier mixed in with my news feed.
I ended up going back to Chrome, mostly due to battery issues with Firefox, however even if I hadn't switched back I think I would have voluntarily turned off all the anti-tracking stuff. It is a data privacy concern, and moreover I hate the idea of giving Google all this data, but the benefits for me were very palpable.
