Out of those three you listed, I would buy Such is Life.  I think it is gonna be a really solid movie.  It's hard to say though, Rage, PBP, and Matchstick are all super legitimate film crews.  I saw the Poorboyz movie at a premier, and it was sick.  Matchstick is the biggest name in the industry for ski vids, and is probably the most quality.  I guess it's your call.  That probably wasn't the most helpful answer, but if I was you, I would buy the cheapest one, and you might be able to get two with a bit more dollar.  Or look at the athlete lists, and see which movie has the athletes your most interested in watching.
