DISCLAIMER: These are my opinions, please feel free to disagree with them. ^^
P.S. This all refers to a party setting, not a solo setting.
Galka WAR/MNK (lvl 24+ WAR/NIN if not tanking)
Mithra THF/WAR (lvl 24+ THF/NIN)
Mithra MNK/WAR (lvl 30-59 MNK/THF, lvl 60+ MNK/SAM)
Tarutaru BLM/WHM
Tarutaru WHM/BLM
Tarutaru RDM/WHM (lvl 32+ RDM/BLM)
Galka PLD/WAR
Mithra DRK/WAR (lvl 30+ DRK/THF)
Mithra SAM/WAR
Mithra RNG/WAR (lvl 24+ RNG/NIN)
Mithra DRG/WAR (lvl 60+ DRG/SAM)
Mithra NIN/WAR (lvl 30+ NIN/THF if not tanking)
Tarutaru SMN/WHM
Tarutaru BRD/WHM
Hume BST/WHM
There are two that I'm iffy about. I'm not sure if SAM/WAR all the way would work well, or if SAM/NIN or SAM/THF would work better once SA and Ichi are available. The other that I'm iffy about is PLD/WAR. Basically, I think if you don't have a lot of money to spend, Elvaan is the best choice, but if you do (which I plan to ^^), then I tend to think a Galka PLD/WAR with two Astral Rings would outperform an Elvaan PLD/WAR with any combination of equipment.
Time will tell, however (when my second character reaches 30 and gets PLD)^^.
