Not that benchmarks matter a whole lot these days, but I think for some benchmarks it was faster than Chrome. It's close enough to not even be a factor, in any case.
Also, it has a feature that Chrome seemingly has no analogue for, and that is: containers.
I never entirely stopped using Firefox. I still use Chrome alongside Firefox for certain things at work.
It had its lows and highs in my opinion. But yeah Firefox on desktop is a great experience right now. Sadly I can't say that about mobile version, it's frustrating to say the least.
