As stated, there is NO comparison in comfort, climber wins hands down.I only use Summit climbers. Hang on's are much more convenient IMO, as once you have them up, you just walk into your spot and climb up ( as long as someone hasn't stolen it!).Climbers are great for hunting public land, or going into a " new" spot, to check out the action before deciding on a permanant stand site, or during the rut, when you plan to sit all day.A climber is definitely a useful tool to have in your hunting gear, whether you use it all the time or just in certain situations.
