I have a set of Bare neoprene and they have lasted reasonable well, I've had them for almost 5 years. They do a great job when the weather is cold and the prices today are fairly reasonable. The downside is if you need to use them during the summer. They are way too hot to be comfortable.
I also have a set of Patagonia Watermaster waders and they are the bullet proof. Since i picked them up I havent used the neoprene's. I am way more comfortable during the day.
It really depends on what your going to use them for and when. Float tubing a lake i'd probably suggest neoprene's however if you fishing during the summer and don't want to wet wade then the breathables are your best choice. Patagonia is an amazing company with a similar enviro ethic as my own and they really stand behind there products. They have the best warranty in the business, only downside is you get what you pay for so they tend to be more expensive then the Bare's.
I have the hodgeman's boots
Planning on replacing them with the Patagonia riverwalker's if they ever wear out on me
