i voted for the original Jungle Hunter. I like the City Hunter design a bit, the helmet was pretty cool, not so much a fan of the face. However, I think more than Jungle Hunter, I really liked Scout and Guardian from the end of Predator 2. I liked Scout's mix of Jungle Hunter with his helmet, and City Hunter with his armor and skin colorations. And Guardian's helmet is just so rad.
And as for PREDATORS, initially I hated every design for the Super Predators. As I watched the movie, Mr. Black grew on me until he took his helmet off and I saw the bastardization they did to his design. It's one thing to try and differentiate this new group from the classics we know and love but that was a bit much. Especially coming off of the travesty that was AVP/AVP:R, without his helmet Wolf looked like trash, as did Scar and Elder. The Classic in PREDATORS wasn't too bad, but like with AVP, his helmet wasn't long enough in the mouth area (his mandibles were jutting out of the bottom of his helmet, as were Scar's if I recall), and his helmet was too wide at the back of the jaw. . From the first PREDATORS trailer, I hated the Falconer helmet. However in recent months he's grown on me, and now Falconer's helmet design has grown on me, more so than Mr. Black's.
