Well, my personal opinion is that Haste Helms and Nova Armors are still the best for the guys (although you might wish to equip stuff that boosts Magic Defense if they haven't maxed it yet), and you can even get 3 Haste Helms per playthrough now (as opposed to only 2 in the SNES version).
The best for the girls has to be the Angel Tiara and the Regal Gown, as I've mentioned previously (but you only get one per playthrough unfortunately).
There are still some items that might be useful, like the Master's Crown for males, which grants Status Immunity and gives a boost similar to the Sunshades (and it stacks with Prism Spectacles
), the Saurian Leathers, a decent armor that also gives +3 speed and +3 strength, the Elemental Aegis seems like a nice armor for Lucca, and the ShadowPlume Robe gives Magus Auto-Barrier (and I think it's his best armor defense wise). This are the ones I remember right now, I might make a more decent comparison tomorrow morning, but I'm going to sleep now.
