Like others have already written: Firefox is the most effective at suppressing ads, _with the uBlock Origin extension_. Ironic that most of Mozilla's funding comes from ad king Google. M's corporate leadership has really driven the project into the ground, and still... Firefox is the only browser that makes mobile Internet usable for me, and so I stick with it everywhere to take advantage of sync for bookmarks (bookmarks being something that someone with influence at M must really hate).
Brave's credulous promotion of crypto currency turned me off, as did what I perceived to be a terrible UI design (being a long time Mozilla user, back to the days of Netscape Navigator 1.0, my bar is clearly set pretty low).
