Familiarity: I've put it through the wringer
The Oakey kitchen sink is a "Poseur Pack", an urban backpack intended more for show than for hard work. Its fine for carrying a laptop and schoolbooks off the bus and into class, but it isn't an outdoors pack.
I have one (my wife bought it me as a present). I used it last year to do 58,000 miles traveling for work in 3rd world countries. It will fit as onboard luggage on intentional flights, and it is well made.
But I wouldn't like to hump it in the bush. It isn't particularly waterproof, its hard to put a waterproof cover on because of the metal junk, it weights too much (again the metal junk) and its not a good design. The cover flap falls back over the laptop, covering the main and secondary compartments. This makes getting anything out a hassle unless its a major "de-pack". Also its only 30L despite its size. Don't believe the "everything plus the kitchen sink" hype. It soon gets full. And its way too expensive for what it is.
On the other hand it impresses schoolkids.... The metal junk make it look very urban warrior.
I spend a lot of time in the military, and even more hiking and climbing. I have had more than my fair share of packs on my back - some good and some bad. I have a good 55L tan military MOLLE pack that I use these days for bush walking. I would have taken it with me on my third world work trips, but advertising yourself as ex military isn't a good idea in some places. It leads to lead poisoning. I took the Oakey instead.
There are far better packs, available far cheaper.
