I also have the Maxpedition Condor II and I've had it for about 6 months now for sure. I can't stop saying how good it is.
With large loads, it's comfortable as hell. I've used it for a 12 hour milsim, packed it to the brim, and it was pure heaven carrying it around. Otherwise I use it for school all the time, carrying my notebook, textbooks, etc, and I've never had an issue with it being uncomfortable at all. The thing I like most about it, is it fits like a glove. It's very adjustable and all the straps hold their position well.
Just about everywhere you look there is molle/pal webbing so that you can add on additional pouches. The only downside is the bottom does not have any webbing, so adding an additional buttpack pouch isn't as easy as I'd like.
The rear compartment (not the main) for the hyrdration pouch is nice, but when you actually have a hydration pouch in there, it can be awkward as the center of the backpack "bubbles" on your back and it doesn't wrap around your body as well. Without the hyrdration it's very comfortable and does wrap around my back very nicely.
The rear of the backpack is somewhat padded along with the shoulder straps. At the same time, I cannot see this backpack falling apart any day soon. That's the sole reason I bought it. I generally go through one backpack every year. So far I've had this one for 6 months, and it's still passable of being brand new. The zippers are very solid, and are larger allowing for less jams, and they have paracord ties on them so that you aren't jingling around as you walk.
As Brakoo said, it's not the biggest backpack though. It depends what you need it for. I use it for school, and it's perfect size. When I've got less things in it, the retention straps can "tighten" up the bag and give it a lower profile. For an everyday backpack, this is a good solution. I can't comment on any other use as I haven't used it for anything other than day-to-day use and our Milsims.
Anyway, I have several Maxpedition gear, and I'm yet to be disappointed by one. Their quality is top-notch in my opinion (however I do not have any of the better gear either).
I hope this helps, take it for what it's worth.
