I have the vortex glass pack, and have been using it a few years now. I like the size and side pockets on it - I keep my wind detector and crossbow cocker in the sides. It also has a zip in the back, nice for places where you have a paper tag. My only complaint is that the hook and elastic piece that's supposed to keep the lid down doesn't work very well. Almost every time I bend over to tie boots or something, the lid comes open and my stuff falls out the top (it's retained by the built in lanyards but still annoying). If I had a redo, I'd probably pay a little more for something with better lid retention. If budget is a big concern (or you don't bend/lean over at the waist much) the vortex is fine.
