I agree the install is critical. That is first and foremost.
Lately I have installed Landmarks from Certainteed, Timberlines by GAF, Malarkey highlanders, IKO, OC's, and Tamko's. The only one I would use on my own home is Certainteed Landmark. I have felt they have been the best for many years now, and I'll still stand by that after using the others. Malarkey's were the only ones comparable, but I am not happy with them. This seems to vary greatly by location. Other roofers,(like Slyfox) who I respect, have told me different in their area and I believe them.
