Duelist bow build VS pure Ranger

Hi all!

I need some advice from you guys, I'm playing with my duelist with bow build and now I'm reached lv81. I found him quite powerful character... But I'm not convince about the ascendency skills that can fit properly for this bow build.
So I'm asking you if is better that I'm gona switch gor the pure ranger?

At parity of build and level, are you think that the ranger it's gonna be more powerful??

I don't care much about %life because I'm die rarely and I have just 2000 of life.

Thank you guys and sorry for my English!
