Put very simply, ground limestone is used for "sweetening the soil"
and hydrated lime (hot lime) is used for sterilising the soil. Ground
limestone is always the cheaper product but not because it's inferior,
its just quarried differently.

Hydrated lime is manufactured, not quarried.

Hydrated lime(WE used to call it sneezy lime) gives you a quick fix
for acid soils, but it doesn't last very long, it can also block the
uptake of Magnesium.
Ground limestone is slow acting and will last for several years, but
you need more to get the same PH level.
