What do you feel is the "best team" of FFIX?

All of them can dish out 9999 in damage, so it is a matter of preference of how you wish to achieve that.

I always use Zidane, obviously, and I always use Quina. No playthrough feels right without eating your enemies for skills. The last two slots are usually filled by a healer and a filler.

I was partial to the first full party of permanent playable characters that the game presented to you: Zidane, Vivi, Steiner, and Garnet.

Zidane, Amarant, Steiner and Freya can all hit the maximum damage for very little MP whilst retaining some useful healing spells. I used them all the time for that very reason. By end game, Amarant's Chakra heals a few thousand health and Freya's Reis' Wind (I think) restored considerable amounts of MP, so more dedicated healers were unnecessary.

Reis's Wind restores HP not MP. That's White Draw. For me I was always switching when I could, but at the end of the game I do favor the main four characters for both story purposes and battle purposes. I always keep everyone around the same level though except for Zidane who would be several levels above everyone else due to main character status.

I loved the 'original' team of Zidane, Garnet, Vivi, and Steiner. Skills and abilities aside, I liked to believe that they all exchanged witty banter in between battles and whatnot.
