I can say I truly enjoy both and they both have their place in my hunting arsenal. There's a certain sense of pride when you walk away from a perfect stand location hung in preparation for the coming season. I hang 15 to 20 hang ons in prep for the season and really enjoy doing it.
That said, I also very much enjoy hunting from my climber. When starting out on new properties, going on trips, and hunting public land, a climber is key.
If I had to chose one stand, it would be a climber hands down.
