7-4 is 12 AP, 525 rank exp, 695 kamihime exp which is 43.75 and 43.75 per ap.
5-4 is 10 AP, 362 rank exp, 475 kamihime exp, which is 36.2 and 47.5 per ap.
Meaning 7-4 is best if you want player exp and 5-4 is better if you want to level your kamihime.
You can run 15-4 if you want to farm items for exchange and get the best exp of that zone. Though a quest with 3stages and x3 mobs on each would probably provide more exchange drops.
