Hmmm. In PLD's case, I'd say the best piece added so far was the hands.

The body NQ is a weaker clone of Reverence+1, the only reason to carry it is still the fealty enhancement. Now, when the +1 comes out, I'd expect it to surpass Reverence+1 body.

The +1 feet are much the same. Still less enmity/haste than Creed+2. And more 5% more PDT on sentinel is as underwhelming as ever.(this being an untested assumption I admit. But it's a reasonable assumption considering the old relic enhancement.)

Hands +1 matched the enmity/haste of enif, letting me store enif. Inv+1! And I was already carrying Valor gantlets+2 for the chivalry enhancement. They also gain 23 MND over valor. A notable boost to chivalry. Last, they have +104 HP, making them the highest HP hands. Good for weakness sets, or just all purpose High HP tanking. It's just too bad no PDT...

Head is as pointless as ever. It does have 2 more enmity and the same haste as Cizin. But the loss of 5% fastcast makes it not worth casting enmity spells in.

Legs are in almost the same place as body. They do have the same PDT, and 1 more enmity than Rev+1 legs. But they lose a substantial amount of DEF and ilvl stats. the HQ will likely surpass Rev.
