My Question is:

Full plate +8/hp
vs.
Chitin +8/hp

On LvL 80 Priest with items:
2x ROC +1
IN
IB
WE +1
LE +1
CS+6
Lycaon Hammer +7
SS+7

Atm, I'm Chitin BP but maybe I'll go back to support priest for few weeks, so i wont change my ROCs to ROLs, actually, I wont change any of my uniques, I'm just wondering if what's better:

AC on Chitin or HP on Full plate


P.S. I have both sets so I wont lose any coins on buying stuff, only on reskill/restat
