My favorite is the Kuiu chugach set. What I really like is the amount of ventilation that can be created using the oversized pit zips, and full length zippers on the pants. In my experience no fabric can be both waterproof and still have good ventilation, so zippers in the right places are a key feature I look for.
On almost all backcountry hunts I also wear gators. In wet conditions I think there vital because they protect the lower legs and boots from wetting out. Good gators are one of my favorite pieces of hunting gear.
Something else I like about the chugach set is how fast it dries when it does get wet ( 8 hrs of driving rain and stalking its just gonna happen). My buddy bought the Yukon guide series from Kuiu, and his dry time was always longer due to the heavy weight fabric. Nothing is perfect, but I think its one of the best out there.
