You all are really sleeping on @Vivaldi . They meet all of the criteria for being a private browser, which cannot be said of several of the browsers on your list.
1. They collect minimal telemetry in a way that the individual user cannot be identified.
2. They have a custom, built-in adblocker that you can customize as well as the base browser features such as third-party cookie-blockign that you expect from a modern browser.
3. They've never opted-in users to features that could compromise their privacy or security like others in your list have (eg.: built-in ad tracking, crypto shilling, and auto-redirects to affiliate links).
4. More privacy-invasive features to allow for functionality that meets the user's privacy and security model are opt-in only.
5. They have made statements clarifying that they have no interest in AI or crypto as products or features for their browser.
6. They deploy stable, timely security updates from the upstream Chromium project.
