Best: Kuiu Chugach Jacket and Pants
Excellent (and quieter than the Kuiu): Core4Element Torrent Jacket and Pants
I think the Sitka rain suit is comparable to the Core4Element, but maybe not as quiet.
I also have the Cabela's MTO50, and it is good as well as being much less expensive.
I personally would pick the Kuiu if packable and durable are your main concerns. The others are not in the same league, in my experience (my experience is somewhat limited since I would rather not spend all my time outside testing rain gear), but the best rain gear, like the Kuiu Chugach, currently needs to be a true hard shell, so it is significantly noisier than some of the other makes. That's why I have the Core4Element for the times when the noise factor is important and there won't be heavy rain throughout the hunt. Not that the Kuiu stuff is super noisy, either, but it certainly is not nearly as quiet as a brushed polyester.
