I had both and i liked them both.
reso is more for tank and oc for dmg.
lol dont macro on wr that is a sin wrs must stay pure and far from macros
how about cruel ,yes ik many said b4 cruel was waste on wr but i tested dmg with a friend with cruel and was superior than oc by far and more tanky, only thing is paralize proc is so good, on wr is not that common but if u macro it will proc more often.
i would like oc more for a def and reso for a raid.
