Honestly, firefox. I've had numerous performance and memory issues with Firefox but from my testing over the years it's the closest to Chrome/Chromium you can get. Also Firefox gets new features fairly regularly. It's still an "innovative" browser, as opposed to Chromium which is mostly stagnant. Vertical tabs are pretty cool. Personally, I just got to like Firefox over time.
