Steel stoves are cheaper and heat up faster. Cast iron is more expensive, heavier and holds heat longer. You can start a fire in a steel stove and heat up the room in less than a half hour, the cast iron could take over an hour.
I've had both and probably give a little bit of an edge to cast just because of the more tempered heat. Surrounding a steel stove with thermal mass could have the same effect.
