I travel frequently and the airlines would always mess up my suitcases, whether it be a broken zipper or a whole.  This luggage set it perfect.  It does get scuffed, but I use one of those magic eraser sponges and the scuffs come right off.  I gave a four star rating because the inside strap on the larger bag broke after the first time I used it and the bag wasn't even overstuffed.  Other than that, I'm happy.

All checked luggage takes a beating from the airlines, but this luggage actually holds up on the outside, which is what I'm most concerned about.  I waited for a while before writing a review because I wanted to see how durable these bags are.  So far so good.
