Hunter exotic armor to prioritize?

400 hours later, I finally made a hunter.

I already got a celestial nighthawk to try out the still hunt/GG combo (very fun), and plan to attune exotic class item to inmost light to get rolls without actively grinding them but the question:

As I get exotic ciphers/engrams, what would you prioritize as the exotic armor to get from Rahool? Bonus points if the applicability extends beyond a single super or subclass. Also bonus points if it is really fun to use or a "must-have" for endgame content.
