The best blind I ever owned as far as ease of setup, room and the windows placed well for me was the Ameristep Roundhouse but they stopped making in around 2001 had one that got ruined on me because I was not able to retrieve it after my car accident. I also liked those zip in floors that were great once the snow came, really helped keep you warmer.
I now have two Barronet blinds that I would put right up there in quality with the Double Bull blinds as far as build quality and material, especially the material they have started to use the last two or three years on the Onx 5 and the new versions of the Pentagon blinds.
My complaint with them is the same complaint I have with most every hub style blind and that is the doors can be hard to enter, I have fallen on my face several times getting both in and out of every hub style blind I have used. The Onx 5 door is much better than the Pentagon door but does not go down to the ground like the old style Ameristep blinds did, I have never had a problem getting into a string steel blind. I also do not like setting up hub blinds as I am kind of short so I can't reach the center hub to pull it up first and have to set them up sides first then get in and push up the center hub. Understand if not for my car accidents and my spinal stenosis that causes my foot to drag a little I may not have this problem but I have had other friends get into various hub blinds and come close to falling as well, they just need to bring the doors down closer to the ground.
