Roof insulation- on the ceiling or under the roof?

My wife and I will be building a detached house next year, and I have a question about it. The house will be built of aerated concrete and will have a hipped roof. There is not much room under the roof, just some storage space. I can't stand upright there, so there will never be any living space or anything like that. Only boxes with some stuff will be stored there.

In our case, should we choose insulation directly under the roof or on the ceiling of the floor? Is there any experience here, which one is more comfortable in winter/summer? Will I notice any difference at all on the top floor? Where can I get a better price?
