The ONLY paint I will put on the exterior of a house is Sherwin Williams. Duration or Emerald.
My house was painted in 1993 with Duration. It's still holding up.
Yes, it's faded. Yes, there are places where it's chipping out. But overall, it's still in excellent condition.
I used SW Porch and Deck Enamel on my Mom's wood porches at her house. Still holding up great when I finally sold the place in 2018. The only problem with it, though, is that it's a latex enamel, which means it's virtually impossible to "bridge" over the small gaps between boards the way you can with the oil-based porch paints.
