The type of units depends upon the civ or types available. I do not like having to fight the same army over again, so usually go for annihilation. That requires some lancers, light cav, or the like.

I do like balance though. Every unit, is supposed to anyways, have good points going for it. We all know this is not true, some are downright useless. Units that can perform multiple functions are better. They can get you out of tight pinches.
