Both Vivaldi and Brave have their advantages, but I had switched away from them. Vivaldi was too slow at times and some keyboard shortcuts in some apps (Google Docs, etc.) didn't work. Brave doesn't support Netflix and some other streaming services (for a noble reason, I believe, but - in the end, it just didn't work).

I used to love and use Opera back in 2000's. These days, I can't find a single browser that has all I want, so I ended up using multiple ones all the time.
