No experience with either one of those. I have an API Bowhunter Extreme, and really like ita lot. No bars in front to get in the way very lite and I have made all day sits in it before. It is quite comfortable. It is also simple to set up and you get the hang of how much lean to start out with pretty quick. The rubber coated bike chain is in my opinion a very good idea for the attatchment to the tree. Stacks together for packing well too. Once locked to the tree it is silent. Have never had a noise problem with it, even in cold weather when creaks can show up.
