ring of diamond skin vs ring of resistance

I have adv prot 4 dragon armor with maxed nunchuks, I am wondering which is better? shall i go for diamond skin rings or resistance? i dont have shield of honor, but i will soon get it, but lets consider i have it, is resistance 2 better or diamond skin? i dont have problems with physical damage also i have iron skin from L menu maxed but i still have problem with magic damage (such as clink, grell, cocodemon, cinder and other these types of magic damage) they deal huge damage to me, any solution? also i heart parry conflicts with cross necklace, is it true? I AM ON NORMAL RLCRAFT.

Edit: i will be making maxed golem armor soon.
