I have both and the Hiker Pro sits in a storage locker. Since getting the Sawyer, I just haven't used it. I like the Sawyer as I use the clean water bag in my pack for my hydration. When time to refill, I just disconnect the drinking tube and connect the tube from the filter. Flow through the filter is very good for a gravity system. I can filter a liter of water in the time it takes me to set up my hammock and tarp.
