Where do you propose we go instead?
The first two are still fairly dependent on the upstream companies - but at least they're ripping out the junk - They are pragmatic solutions in the short term.
Ladybird is nicely independent in the sense that's truly one of the few offerings that isn't a derivative of Firefox/Chromium, but it's not "ready" yet for most daily uses.
But seriously - please don't fall for the Mozilla marketing that Firefox is some privacy beacon as an alternative to Chrome. It's marketing not reality.
