Personally I would go with the pac, save up and go for the ultimate, amazing build quality, fully waterproof, and an unconditional lifetime warranty, and yo can compress it down when you don't need it to be massive, and the x strap clips out of the way when not in use. however you can fit shitloads in it/on it when you need to, one of my best loads so far includes:
My full toolkit
14 pizzas
6 ready meals
2 boxes of cereal
2 bags of baby bel
