too many of you are comparing SAINT against sram and its like comparing goats to a car - saint is a DH specific group and sram does not make one - XO to XTR - X9 to XT , thats how there placed on the market - all of it works better in different areas, its how you ride and not what you ride. if you want the highest durability in either product then dont bye the top level, your only saving weight and that comes at a price - ask any rider who did the Trans Rockies race and the ones who made it the whole 7 days without 1 issue, were using X9, XT, even SLX. if you want bling then by the best, you can even get your favorite color "pink" in XO,
