The beauty of Rift is that there is only one class for each armor class, eliminating low level confusion. Later you'll want to adjust and prioritize, but for leveling purposes you can just be confident that chain is there for clerics and only clerics, and it therefore has the stats clerics need. In this case that's Wisdom, Intelligence, and Endurance.
Cloth tends to have more Int than Wis because it's for mages. There's not much reason, if any, to ever take a cloth piece. Every quest has a reward of each armor type, so there will be a better chain choice for you. Rolling on cloth in a group situation where there is a mage present is sillytalk.
In other words, just take the chain.
For further reading, Callinon has a nifty post about what each stat does for each class that I thought was stickied in the callings forum, but can't seem to find now. Anyone have a link?
