We're at a really dangerous point with browsers at the moment where there's really no consumer-friendly option available. I'm scared to say that Safari comes closest but you're just in Apple's walled garden then instead of someone elses'. Our only hope seems to lie with Ladybird, if that even ends up being good and it seems extensions aren't on the agenda at least for a while.
Have you heard of Brave? It's a great browser with a built-in ad blocker founded by Brendan Eich, one of the co-founders of Mozilla and the creator of Javascript. I'm not a shill, I swear - I just think it's a great initiative that should be more well known than it is.
Every browser alternatives you can reasonably choose today is going to be either Blink (Chromium-based) or Gecko (Firefox-based). And then you have WebKit (Safari).
Ladybird, Flow and Dillo are really the only true alternative browsers in active development other than a few others running on niche operating systems (to which I'm throwing in all of the DOS browsers...).
