Definitely worth the sticker shock. I'm still figuring out all of the features, but overall the Xenon has way exceeded my expectations. The custom moldable hip belt is genius, it keeps the pack right where you want it. It's really easy to adjust for optimal weight-bearing, and I especially liked that I could shift the weight around when a body part got sore. Love the bottom zipper, makes for easy access to larger items and overall better organization. The sizing is similar to other Osprey packs, but I recommend trying it on if possible. By torso measurement I should be an xs but a small actually fit better.
