I think what was being asked is if there's something like Brave that doesn't use a webkit derived back-end. Good defaults and a good stance on privacy is one reason to use Brave and historically Firefox, but another is that it keeps the browser ecosystem from being too homogeneous. Firefox is the last browser with over sub-percent market share, and even then it's less than 3%, so it's almost gone.

A case can be made that many of the browsers split from webkit (or split from things that split from webkit) long enough ago that there is competition, but IMO that's a far cry from a fully independent solution.
