FYI Chrome has always had bookmark and browser sync for iOS, although unlike with Safari closing a synced tab on iOS doesn’t close the tab on the Mac.
I use Brave on the Mac - it’s Google’s Chromium engine (also used by Microsoft’s browser as well as Opera and Vivaldi) with Google’s tracking code ripped out, and with ad-blocking built in (plus the ability to use hundreds of useful extensions that have no equivalent on Safari). I find it almost always faster than Safari, though, like Chrome, it can be a RAM hog. (But I have 40Gb RAM, and usually have a dozen tabs open at any given time, and it’s not a problem.)
Brave on iOS has sync - it’s a little more primitive on iOS, but it’s still in development.
