Chromium is not Chrome. It does not have auto-update. Surprisingly this gives more control by default than with Firefox.
There are forks that try to strip Google from it, but it is a mistake to assume that Chromium is somehow better than Chrome.
What other integrations, specifically please, does Chromium have with Google?
Aside: do Google serve the Firefox Newtab adverts, perhaps that "feature" was added for the extra money Firefox are getting from Google?
1. It uses Google DNS internally, bypassing system DNS.
2. First-run analytics to Google, new tab page analytics to Google.
3. Various built-in google services that phone home: Google Host Detector, Google URL Tracker, Google Cloud Messaging, Google Hotwording, Google Safe Browsing, WiveDine DRM, Google AutoFill, etc.
4. Update checks for all these components (the browser does not have update, but the rest does).
5. Countless accesses to Google, such as geo-location to find nearest Google server, ping probes for connectivity, etc. For a list of domains that are accessed by Chromium, see this regex used by the ungoogled-chromium project: https://github.com/Eloston/ungoogled-chromium/blob/30969fddf...

I see no problem with neither Chrome nor Firefox defaulting to Google search and suggestions, as that is easily configurable for normal users. All of the above, however, is not.
This is not true. Firefox explicitly asks you the first time you start typing a search in the location bar whether to allow search suggestions. It is opt-in.
Firefox also allows you to keep the location/search bar separate so that you can have search suggestions without sending every URL you type to Google.
tl;dr : Choosing anything based on Chromium is giving the death sentence to the Web "democracy"
Moving to a Chromium based browser is letting more and more market share to a browser engine whose roadmap is fully determined by Google. The issue trackers of Chromium or Android projects clearly shows how much Google values its users'feedback about their most wanted features : Not At All. These days it seems they are starting to feel the same about open standards... At first with WHATWG getting in the yard of W3C they tried to get more influence on the redaction of standards, now they don't even bother since they can force anything they want in a "de facto standard" as they are doing with AMP.
The next step is to obliterate any standardized feature they don't like. It can seems to be a frivolous issue but they are doing this right now to SVG-in-OpenType, a standard that is currently implemented in all major browsers except Chromium family (yes even Edge see https://www.colorfonts.wtf/#section4 but the switch to Chromium will probably end it). Here is what Google responds to the numerous people aking them to implement it : https://bugs.chromium.org/p/chromium/issues/detail?id=306078... Apparently a feature even the -probably small- team of Edge developers managed to implement is too complicated for Google chrome engineers ?!? This will get more and more frequent as long they have more than 80% of browser marketshares.
So if you switch to ANY Chromium based browser, even if it's for privacy reasons, PLEASE keep in mind that you are working for the destruction of the web "democracy".
