For practical gear comparison, consider 1 point of STR equal to 1.75 points of INT. Barring diminishing returns or a stat cap, STR is always the right choice. Only the head slot is particularly contested because PGL can stick INT up there; this makes a cavalier's hat or silver tricorne with INT materia our best non-r/ex option. However, if you have a paragon's crown, you would need multiple INT materia to create a hat superior to that.
Regarding potency materia, the only viable slot is feet. Weapon DMG is second biggest factor (next to level difference) when calculating damage output--magicked fists or not--so it would make little sense to swap out Ifrit/Mogfists for inferior weapon DMG + magic potency.
The feet slot is sorely lacking in the DD department, at least for now. If 1.21 has good r/ex options (STR, INT, ATK, some useful AF gear), potency materia will be a hard sell--assuming it does anything at all.
