If both fit equally well, you get the luxury of choosing the better feature set. Here, the best thing to do is take your gear to the store, and pack them both as though you were heading out for a typical trip. With these two packs, that may not be possible, so you'll have to do a "virtual" packing by what's on the website.

You're trying to figure out which pack fits your packing style, which is driven to a great extent by how you hike: do you need pockets for camera gear, snacks, route-finding equipment (GPS or map and compass), water bottle, water filter, and other things you use a lot while you're walking? Do you want a lid pocket to keep all the little stuff in? Or are you the type who doesn't get into the pack much during the day, and doesn't need pockets?

If you could post how you pack and use your pack during the day, maybe some of the folks who use these two packs could give you an idea of which works better. (I'm not familiar with either pack.

Good luck.
