Generally speaking you'll see more of everything as your gear goes up in iLvl because the higher budget means more stats in general. You'll also see different pieces in a given set of gear have Piety than in other sets.

Mind is your most important stat. If it has more Mind, you probably want it. If it has a lot more mind, you almost certainly want it. As you get more pieces, the Piety will tend to level out. Unless you're trying to min/max for progression content, that simple rule will always work. For materia, you likely never need to use Piety.
