Which is higher quality? A pure wool coat or a wool/nylon/cashmere coat?

I am interested in buying a wool coatI found one I like that is 70% wool, 20% nylon and 10% cashmereHow does this compare in quality to a coat that is 100% wool? Would the blend be inferior even though it has some cashmere in it?Thanks!
