Same reasons I chose the G2. Any Bakflip model will do the trick, it just depends how much weight you plan on putting on top of it. It probably is safe to assume that the models that hold more weight are probably a little more durable. They just weren't worth the extra $$$ to me as I read plenty of good reviews on the G2.
