What is the best armour Guthix Zamorak Saradomin or Armadyl and why

In my opinion, Armadyl as I love ranging. It is 45m gp approx and is a member item. Guthix, Zamorak and Saradomin are all rune armour and non-member item and all their price cost around 3-5m gp approx and only give stats of normal rune armour.
