I am a very big fan of MAS products in terms of product support, reduced allergic irratants, and the non-production of amine blush, and so prefer to use their products. I have used WEST System and System Three products for decades now, and like their products as well. For no particular reason at all, I have never personnally used Interlux's epoxy products.
I have always appreciated WEST System's innovative thinking, ongoing research and their willingness to share the data that comes out of this research. As result, for many years I typically used their products, despite their slightly higher cost, as a way of supporting thier dedication to advancing technology.
My sense is that used properly either MAS or WEST products will produce equally high quality results, but in recent years have switched to MAS because IMHO MAS is just an easier product to work with and live with.
