Kokatat is tried and tested, completely dry and made in the USA. I just sent my Drysuit in and they are repairing a tear, pressure testing it and repairing and other pin hole leaks... all for $20. In my experience Kokatat has been the only clothing company to make actually "dry" pieces of gear, and then on top of that, if you make it "un-dry" by putting a hole in it they will repair it for virtually nothing. If all you have is pin hole leaks they charge you 5 bucks make it completely dry again.. Every other drytop I've owned has become a "wet-top" within the first 50 days of use.
The Gore-Tex Sweet looks pretty tough and is Gore-Tex... but you have to pay extra cause their Euro and there isn't much beta out on it so IMO Kokatat is the safest choice - local and beefy, but the Sweet might be just as good.
