Firefox with uBlock installed gives a much faster overall experience on my device compared to using Google Chrome. Ads have become such a nightmare on mobile sites.
When did you last try it? If it was anything more than a month ago you might want go give it another spin, and/or try a Beta or Nightly build, as the Quantum revamps aren't all enabled yet in the stable channel of the Android edition.
I'm pretty happy with Firefox Focus on a Moto G3. Some people may not like the lack of features in that browser however, e.g. no history, no cookies saved, etc.

That's kind of the point of Focus, it's meant to be a private browser. You can also get regular Firefox with uBlock Origin to have a similar experience with these features, if this annoys you.
