For any large block of infantry, you probably want either 30+ or minimum size. The only ones you'd want minimum size are the units taken for reasons other than close combat, such as shooting units, point fillers, mandatory units, or ones taken for other reasons (like clan rats taken so you can get the attached special weapons team).
So 30 is definitely the minimum for any normal block of infantry, and that's probably a good size for skeletons. With ghouls you could go larger, as large as you like in fact, because they're a bit more cost effective. In fact, the only reason I'd take skeletons is for standards, and possibly holding characters. Otherwise, ghouls are a better unit.
