I think Taru's look the best in ALL AF...I know my opinion is bias but we do look the best in AF. Here's my list of favorites from best to worst.
1. DRK AF 2. BST AF (especially the beast helm) 3. MNK AF 4. SAM AF 5. DRG AF 6. BLM AF (I think taru look the best with it on..everyone else looks bleh) 7. SMN AF 8. NIN AF 9. RDM AF 10. RNG AF 11. BRD AF 12. WAR AF 13. PLD AF (sorry I just don't like how PLD AF looks) 14. WHM AF 15. THF AF (cause it looks silly on any race)
