I get people wanting an alternative Chromium based browser. Vivaldi, IMO, is a much better than Brave, and doesn't have all the annoying crypto weirdness.
If you care about privacy, don't use Vivaldi. They're closed source so no matter what they claim there's no way to know if they're actually following their word. If you care about privacy and need to use Chromium, Ungoogled Chromium is good.
