I'm posting this comment on Brave, having switched over last week for most of my personal browsing. Generally like it a lot; there are a couple warts (it won't open S3 URLs from the AWS web interface, for example), but it does most of what I need in a browser.
As a replacement for Chrome on your PC, Brave takes the second approach, and performs the evaluation locally (pulling down a fresh list every so often for up-to-date comparisons). You'll have to check with Vivaldi on which approach they take.
Brave has all of the phone-home-to-Google logic removed. If you ever spot anything at all that gives you concern, do feel free to let us know.

After having just posted here, it was...disconcerting. I'd like to give you guys the benefit of the doubt, but you may want to check a fresh update & relaunch from 0.23 to 0.24. I doubt I could reproduce (I've already clicked past it, and it was only on the first re-launch), but for a moment I was pretty confused about what browser was open (in fact, the only reason I'm certain it's Brave is because I just double-checked my Chrome and it's still on 0.68). Brave 0.24, V8 6.9.427.23, rev f657f15, macOS x64 (10.11.6 El Capitan), OS Release 15.6.0, Brave Sync v1.4.2, libchromiumcontent 69.0.3497.100.
* You can uncheck Firefox's "Play DRM-controlled content" option (which will delete the DRM blob from disk). https://support.mozilla.org/kb/enable-drm
* Or you can install one of Mozilla's "EME-free" builds of Firefox. The only difference between regular and "EME-free" builds is the default value of the "Play DRM-controlled content" option.
This is ungoogled chromium: https://github.com/Eloston/ungoogled-chromium
Two things to note from that thread:
From what I've read, Mozilla had some agreement with Google to keep all the data from their tracking stuff silo'ed so it wasn't aggregated with other data and wasn't used for anything besides showing back to Mozilla people.
and
They're now (and have been for more than a year) respecting DNT, removing the GA code so that you don't make any requests to google if you have that enabled.
As for Firefox including Pocket, they own Pocket for starters, and it's less annoying than Edge or Chrome pushing their analytics filled services. There's a lot less cruft on Firefox than in other browsers. If I really wanted I could use one of the GNU forks of Firefox, though I'm not sure how much more privacy conscious they may be aside from a bunch of brand rework.
And I also got burned by the very badly managed WebExtensions thing. I can totally see where GP is coming from.
Edit: actually, there should be more browsers that I don't know about because I haven't really looked around anymore since choosing Firefox a decade ago. Is anything as well-supported (in terms of proper rendering and security, as well as being FOSS / privacy-conscious) that I should look at other than ungoogled chromium?
