I can't recommend any particular brand, I'm real lucky if I get 2 seasons out of any of them, and that usually requires some repairs (I have not tried Simms). But I do a lot of hunting, and walking through some brushy areas. Basic question is how much walking you expect to do vs how much standing in water (and how deep)? I do a lot of walking so i always buy breathable. But i have a pair of neoprene also that I occasionally use when I foresee standing in cold water. If you are hunting big water you could also argue that neoprene provides some safety factor since they provide some degree of flotation and insulation in an emergency.
Regarding breathable waders, I try to get ones that have the leg seams on the outer leg, if the seams run down from your crotch to the boot they seem to quickly wear out due to rubbing against one another.
