I'm a Sitka fan, but also like First Lite. I currently own all Sitka, so I won't be switching brands anytime soon. While the Kuiu stuff is pretty good overall, my experience has proven that GoreTex is a better fabric than Toray, when comparing them in wet conditions. If you've ever worn GoreTex waders, versus Toray, you'll notice that the GoreTex definitely breathes better. My biggest decision between Kuiu and Sitka was the factory direct option, versus using an actual retailer. I like buying most of my gear through the same store, so the Sitka gear allows me to do that. First Lite is carried by one of my local shops, so that's why that would be my next choice.
