Rabid has toughness and precision.
Carrior has Vitality and Power.
(if I'm correct)
So it's about the big argument which is better? Tough or vit? Is you opponent raw dps or condi's? (cause toughness is useless against condi's while vit is viable with both yet less effective than toughness with raw damage).
But there are forum topics everywhere where they calculate the differences between tough and vit.
I prefer settlers for condi ranger
