Any chance of getting some elaboration on the advantages of the Guyot design? Thanks

First off the Guyot is 32 oz which is the exact size for the Katadyn Mircropur tabs that I carry, I don't think the Klean Kanteen makes a one litter bottle. Also the Guyot just feels more substantial to me and I really like the cordage system on the bottle for securing it to gear. Both are really nice bottles, for me the Guyot just fits my system better.
