The backpack harness is the main reason I switched to this bag from the Peak Design Travel Backpack. Their backpack straps are an afterthought and the bag is uncomfortable at even reasonable loads. This bag puts the harness first and we're rewarded with incredible comfort and security.
The camera side access is the right size and is easily accessible for quickly pulling out a camera of any size.
The top catch-all compartment is spacious and the bag can hold a huge amount of stuff without *looking* like it can hold a lot, which is great.
There's extra latches, straps, strips, hooks, and loops for anything you'd want to add to carry on the exterior of the bag.
Many other pros not worth mentioning are just standard feature sets for this bag.
The access into the bag from the back side (the side against your back as you're wearing it) is cumbersome. If you use a camera cube, this is the only way into your camera gear which makes sense from a security perspective, but it does make the idea of switching a lens or grabbing a microphone something I think twice about. This is also the way into the laptop compartment...again, not the easiest to get at.
