PLD Gear?

Physical damage mitigation from VIT comes from the amount of DEF that VIT adds. So, you have the same problem with VIT, but you get less DEF from your VIT than you get from stacking DEF directly. By stacking VIT you can make up for this with magical defense and enhancing magic potency. So tbh the effectiveness of DEF or VIT is kind of a wash and is more up to your own play style.

I have seen absolutely no testing on magical defense. For this discussion, we can assume that m.DEF suffers from the same dlvl curve as DEF. So the debate really comes down to what do you want to achieve with your chest piece. Do you want physical damage mitigation, HP, or a mix of m.DEF/DEF/enhancing magic potency? You then need to weigh the effectiveness of each against the stats of your other gear and decide what's best for your build.

I think the biggest thing you can take away from that testing is that anywhere you are effected greatly by Dlvl, your best option for damage reduction would be VIT > Def.

Not for the Def/Mdef but for the Block value you get. Since it's a straight % gain per stat, with a limited effect by Dlvl. (now that it's fixed)

So 100 VIT or 100 Def over 1000 Damage Attack (physical)

VIT - 100 HP, 66 Def, 66 Mdef, 10% Block - 989 or 900 when blocked
Def - 100 Def - 980

With Divine Veil always on cooldown you're 20 sec/min @ 100% Block
so say every 5 seconds you get a 1000 damage attack.

VIT - 60 sec - 11512 Damage
Def - 60 sec - 11760 Damage

From estimated calculations of Ifrit, that it would take near 1900 Def to reach the damage floor, and what appears to be around 1600 to see any great benefit.

Calculations aren't exact, but are used to give a close idea
