Ask HN: Which iOS web browser do you use? Why?

Firefox have released a new iOS browser. There was some interesting discussion here - https://news.ycombinator.com/item?id=26272710.

It got me thinking, I have little idea what the "best" browser setup is for iOS, especially in terms of privacy, but also usability and unique features.

I currently use Safari with the 1Blocker add-on. I notice that DuckDuckGo has a browser, what are its advantages? What about Firefox? Or even Chrome?

What browser do you use? Why? Is there native support (or the ability to include add-ons) for ad-blockers or enhanced privacy?
