My wife prefers her Deuter ACT to her Osprey, though hers is not the Aura. I have an Atmos (the male version of the Aura) and LOVE it. Make sure the harness adjustment is dialed in (see pack fit) as it will effect how it rides on your hips. The hipbelt adjustment on the Aura is very easy and effective. It really depends on body type. My wife's Deuter has held up very well, by the way. I've only put 300 miles or so on the Atmos, but it shows zero wear. Basically, both great packs, just need to find the perfect fit.
