better DEF.
Chainmail has 21 DEF
Chainmail +1 has 22 DEF
for something that are +1, they will add in different stats too.
you can always take a look at them in the AH and see the difference. some are slight variations, and some are quite impressive.
take for instace the Wolf Mantle
Def: 4 Vs. Light: 4
now the Wolf Mantle +1
Def: 5 Vs. Fire: 3 Vs. Ice: 3 Vs. Water: 3 VS. Lightning: 3 Vs. Earth: 3 Vs. Wind: 3 Vs. Light: 3
hope that helps
