Moogle Fists

And if you have the money to afford good melds on gloves/ pants then you most likely have the money to afford Giantsgall which far superior to all three mentioned.

I don't understand your reasoning. Giantsgall becomes less valuable when you've already reached cap through other means. The way I figure, the main attraction of Giantsgall weapons was melding primary and secondary stats to close the gaps for people who could not fill them up elsewhere.

Let's say you've already geared yourself to 350/310, which is good enough for Ifrit/Moogle/Giantsgall.

Ifrit has +30 ATK
Moogle has +30 ACC.
Giantsgall has effectively +10ACC, since the INT is irrelevant at cap.

The one advantage Giantsgall has is melding, but what of it? MNK can't meld ATK. You would need 3-4x STR meld to get an ATK value equivalent to Ifrit. INT is useless now. The only other thing is ACC, but you must meld over 20ACC to supersede Moogle's bonus. If you were really hurting for accuracy, it's easy to make a case for Giantsgall. However, weapons in FFXIV have been transient, so I have always been suspicious of expensive weapon melding.

If I already had these three weapons in my locker, I would use Ifrit with ACC food/high ACC situations and/or moogle with ATK food/low ACC situations. Giantsgall would be money.
