I'm not sure how this one compares to other agility sets because this is my one and only set I have purchased. It is very flimsy and not at all sturdy. If you are going to use this in your backyard, you will need to make sure to hold it down with some sort of rock or other material because it is extremely light. The joints are very weak and not well fitting.
