Their advantage over say.. levy units probably should be that because they're usually police / garrison units of sorts, they should have better effect in terms of that, this is easily doable , the rather underutilized "is_peasant" trait in the EDU does percersively this, units with this trait only count as half towards the garrison effect, so it is stand to reason that all levy type and a good portion of the other free upkeep types in general should get this effect(for example the sergeants not directly under you may be as much of a deterence to maintaining order as an aid...), thus forcing you to build more militias to be able to reasonablly hold settlements , espeiclly those further away.
