The Osprey is almost 3x the price of this bag and it's hardly fair to compare. In this case, given Osprey's reputation, the price increase is justified as their quality tends to be superior to cheaper products.
I don't have the bag from this drop or the Osprey bag, but I do have other Osprey products. Generally speaking, you get what you pay for with Osprey and this is also true on the other end of the price spectrum. I would confidently guess that this drop is a cheaper alternative to Osprey, not simply an analogous bag to consider.
