I don't have any experience with Snugpak, so I can't give you an opinion on it. The Kelty has 2 external cinch straps on each side, and it appears the Snugpak does not. Those cinch straps are really handy for snugging small/light loads close to the body for balance, and helps to prevent small loads from rattling around when on the move. They may also help to relieve stress on the zipper of the main compartment if stuffed to capacity. As an added bonus, you can always clip a flashlight, Carabiner, or something to those straps. They can also be useful for lashing a tripod or tent poles to the pack.
