As a duck hunter, I have been through some rain gear...
Currently I use a Sitka Delta (which is a jacket made for duck hunting). Best jacket I ever owned for keeping dry under really wet conditions. I would say it is over-priced, but were I to lose it, I would buy another one tomorrow. Might not stay dry in a swimming pool, but I could stay dry in the shower with it.
My father has a Kuiu Yukon, and the Sitka. He likes the Sitka better for duck hunting, but only because it is more well-organized and designed towards duck hunting. I have a friend that has Sitka and First Lite, and prefers the Sitka for ducks, and the First Lite for big game....
Bottom line, is that for staying dry, I do not think you could go wrong with Sitka, Kuiu, or First Lite gear. All quality stuff, that will keep you dry.
