I can't comment on those two--they don't come in a size that fits me. The best wearing, best fitting boot I've found in the Muck "Woody"--I love it. It gives very good support (I got to have that), very comfortable, and plenty warm for MS weather. For cold weather, or cold feet, there is the Woody Max with extra Thinsulate. They cost a little more than the ones you listed, but they are the best (for me) I've found.
