Sorry., as an association we are limited in our comments. I always recommend looking up the product approval on any system which will indicate that it has been independantly tested, produced under a quality control program with third party auditing and reviewed to the building code. It will state the products limitations for application, slope, fastening etc. This is the best way to compare.
