First, all of these stands are only adjustable in one dimension (front to back). This forces you to rotate the stand around the tree to find the point where the base is level (side to side). There are only two points on the tree for which this is true. You are limited almost as much as the stands that require a vertical tree. The Johnson 360 can be positioned anywhere around the trunk. This allows you to put your climbing device in the safest position. The Johnson 360 allows you to take advantage of the best positioning for game trails, view through brush, and feeding areas without sacrificing safety.
In addition, all of the stands questioned have other defects. They have small platforms which limits mobility in the stand, the ability to stand up while shooting, and ease/safety of entering/exiting the stand. The Johnson 360 allows adequate room for feet wearing boots and plenty of room to stand up beside the seat.
All of these competitors require lubricants which stain clothes and give off odors. The Johnson 360 uses no lubricants, but is completely silent.
The seat of the Johnson is designed for comfort. Besides adequate padding, the seat is adjustable to your height so your legs don't fall asleep. It offers back support to avoid fatigue and support posture while shooting.
