Vivaldi. Most configurable out of the box (which means I can theme it to match the colors of my channel), has good privacy and security (it has a nice configurable built-in adblocker), and is pretty fast. My only real complaint for Vivaldi is it's not completely open source.
Brave as a backup.
Firefox is shit; owned by facist, far-left, evil, anti-freedom Mozilla. Firefox used to be good, but over the years it has been corporitized and trashed by Mozilla. Mozilla also added hidden telemetry that is not disabled when you "disable" telemetry... and they also added ads to the browser. Adding to this pain is removing features users wanted to keep as well. It's also slower in general than chromium based browsers.
I would prefer to see all linux distros not include a browser and just simply make a GUI where users could pick an alternative of their choice.
Opera is now owned by a Chinese company and is basically spyware. I do use Opera GX on Windows 10, but only because I can cap resource usage whenever I stream (my internet sucks, so the bandwidth limit in Opera GX is nice). The original CEO left Opera and eventually went on to make Vivaldi.
Chrome and Edge are also spyware. Both of these are owned by big tech companies who make lots of money off of data harvesting.
I like Epiphany as a lightweight browser (which fits right in with the Gnome/Budgie stack, unlike Falkon), but it's not in the repos anymore?
