Darklight Corselet would be prefered by some that's for sure. I personally went with the Overcoat because I can also use the coat on BRD, MNK and THM/BLM. The Tabard looks nice however It doesn't look as appealing for MNK (Int on the coat puts me at near stat cap for INT), and unusable for BRD and THM/BLM (guess you can say I went for more balance between multiple jobs, lol)
