Kent Faststeel has always been a quality shell for me. Breaking a shell open the components all look top notch and shot is round like you would expect. They can get a little pricey at times, but they cycle well and haven't let me down.
Neoprene are just more comfortable and warmer for me. It seems like the boots are always higher quality and more insulated than breathables, and my feet are the first thing to get cold.
