I think in the EB time period, levy hoplites would be mostly used as garrison troops - used to defend a city and its home territory, but not to go invading other people's lands with. On the offensive, classical hoplites, or more modern hoplite or phalangite units, would be used. So it partly depends on the situation.

Unless, of course, your faction's financial situation is desperate, and you can't afford anything better. Beggars can't be choosers.
