LIbrewolf will basically be a 1:1 for firefox, minux the bs, if you want to stick with that. They keep a newer codebase than waterfox.

Vivaldi I generally like, though I had some issues on my linux install... but 50/50 it was something I was doing specifically. It's a solid browser.

I keep Helium around for when I just need a plain vanilla chromium browser because sometimes you do for some sites.
