I have both and both are great quivers. But IF I had to decide on just one it would be GN! Just a good solid well designed light but sturdy quiver that works really great. I personally like how it groups the arrows in a tight bundle rather than all fanned out! As for the two inside back arrows being tough to get out I assume so for target shooting but for me in a hunting quiver I hardly ever use two of the front 3 arrows much less the inside two.
But with all that said the TH is a solid quiver that weighs more but is quality through and through. And it just LOOKS classier.

I'm with R.W.  The Kanati gets my vote also

I start by saying I hate bow quivers. I have had Kanati's, Big Jim's. I recently ordered a Thunderhorn small fry Linx. Sent in pictures of my bow. I got it and it matched perfect. Put it on and it fit very snug. Shot it and liked the way my bow felt and shot. No experience with the Great Northern.
