I exchanged an REI Mars for this and am extremely glad I did. I tend to do a lot of dayhikes, but about 3 times a year I do multi-day trips, mostly into the Rockies and Sierras. As a result of these locales, I'm generally carrying a bear canister which fits nicely inside the main compartment. My BearVault BV500 even fits lengthwise side to side. The straps on the bottom hold my tent nice and snug. The waterproof front pocket is great for keeping my cell phone dry when the afternoon showers hit. And the large side pockets allow me to carry my Nalgene plus 3 more for my young children.
One great feature that adds to the versatility is the removable frame. This allows me to convert it into a rucksack for those shorter dayhikes.
I've carried loads up to around 38 pounds and this pack carries like a champ. I'll be wearing this pack until it falls apart, which, so far, seems like it'll be a long time from now.
