I use both but i like my climber better. I can be in my tree in less than 5 minutes ready to take a shot! Yes I have been busted half way up and on my way down but, no way around that! I like to lean out at times and just feel more stable leaning against the rail, it steadies me. I also have my video camera swing arm on the rail of my climber. I set my bow/gun on the rail. I tend to use the hang-on in the early season, field edges and what-not! Good luck!
