I've done a round-trip through a few browsers in the latter half of last year, and now I'm back to Chrome. It's usually sync that was too broken for me to use. Chrome's sync works nearly immediately. Firefox on Android would stop syncing open tabs so frequently that I barely remember it working at all. I had to log out and log back in from my Firefox account to get it to sync. But an hour or so later it wouldn't work anymore. Vivaldi has better sync, but it seems to just randomly break a LOT. It would recover itself after a while, so in that sense it was superior to Firefox. (I liked Vivaldi's amazing configurability, but it's lack of bookmarklet support was breaking some of my workflows too, so in the end I abandoned it.) I tried Opera too, but I think it had similar issues and I abandoned it quickly. Syncing extension settings (the settings of an extension, e.g. custom filters in uBlock Origin) seems to only be supported on Chrome. Firefox doesn't have it.
