Just upgraded from a Fade Crunch to a Dynamic Disc Ranger. Those aren't the styles in question, but they are the brands. So I'll give you my overall opinion of the brands.
The Fade brand is built pretty nicely, it's good material and the drink pockets are lined with material that keeps water cool and doesn't allow condensation to seep into the fabric, making your bag wet.
The Dynamic Disc bags don't have that feature, so the pocket for drinks gets a little wet if the drink is cold enough. DD uses very high quality material and the bag will last a long time. DD also has a lifetime warranty on their bags should something happen that hinders the intent of the bag.
Having the Fade Crunch, it had one strap which slightly torqued my back after a day of play. The Fade Tourney also comes with one strap, so you will need to look into purchasing shoulder straps if that's a concern for you. However, the Soldier also comes with one strap, so it's got the same problem.
I was tempted with the DD commander, but ultimately chose the Ranger due to its storage options and backpack style. I wouldn't have chosen the Soldier because it's only a small step above the Fade Crunch.
Hope that helps a little bit, good luck with your research and bag of choice.
