The title is err, not correct because the top 2 alternatives Opera and Arc are based on Chromium engine. I have seen tons of people swear by Arc, but I am seriously asking (since as a Linux user I can’t use it), how much good can a browser be in this day and age if ultimately it’s ad blocking breaks and it will since Manifest v2 will go soon(unless Arc folks have a solution for it)
The rest alternatives are Firefox, Zen (FF fork but honestly Atleast this was something new I learned from this article) and Tor (which is weird since it is not meant for normal web browsing and using it will not only be slow but put additional strain on the nodes, correct me if I am wrong).
I gave Vivaldi a try way back in its early days when I was on Windows. IIRC, it was bundled with lots of features even then and I think, for some weird reason, had Philips Hue Lighting support integrated (unless I am really confusing it with something other, this is multiple years old experience of mine).
I used it as my main browser for Atleast couple of months then.
