I had a fracture red ranger and now the quasar blue, I can say the bottom and sidewalls seem to be much thicker on the newer bag.

-Ranger doesn't stand up straight, they lean.... No idea where you get this from mine is perfectly straight up and down. Side Note: My buddies grip bag has to be loaded a certain way to prevent it from falling over. On a typical round his bag topples over 2-3 times, whereas mine, never.
-Ranger didn't have rails. Yes it does not have rails but it does have feet that keep it off the ground. We played a particularly muddy mountainous course on Saturday, you would have had no idea by looking at the bottom of my bag.
-Storage in the ranger is amazing. You really have to drive this point home, especially for winter golf, I have packed hand warmers, a sweatshirt, a coat and 2 pairs of socks in the top with my other accessories (wallet, retriever)
Compared to my buddy's grip there is no way I would trade my Ranger for a Grip, I completely understand that the Grip is more durable, yada yada, but for the design, price, and function, I would go Ranger.
