I have the AGC and had a Badlands. The Badlands was good with the magnetic closure for convenience and the lifetime warranty is awesome but I prefer the AGC for the pockets and versatility in organization. Plus, I liked the shape of it better and the top of it is more flat, making for a small shelf to place a protein bar on as I get a sip of water (Yeah, it's trivial but I figured I would mention it).
I recently made the decision to go with the Leupold RX-1600i. I thought about the Vortex for its lifetime warranty but then thought, it will probably go out like most rangefinders in 7-10 years and at that time, I will probably want to upgrade to something that is out then that is better anyway.
The Leupold fits in the front pocket perfectly and the AGC has a leash that can attach to the rangefinder so if it gets dropped, it doesn't hit the ground or roll down a hill. I also hold my Garmin, light and other small items in the side, bottom and back pockets of the AGC. One last thing, the price of the AGC is not outlandish which in my opinion sealed the deal!
