Most classes will, more than likely, be stronger than jobs assuming full allagan+allagan weapon. That's a pretty steep assumption, though.

Exception is MNK, but if you have a second MNK applying DK then PUG would probably be better. This would mean PUG has 0 AoE, and would TP starve even faster, though(VB).

This is just eyeballing it, but jobs don't REALLY offer much, except for SCH/WHM/PLD, and if tanking then WAR.
