3. A combination of spray foam for walls, joists and basement and cellulose for the attic will give you the best possible insulation solution:

Our customers commonly ask what the best possible type of insulation is for their home. We recommend spray foam insulation, which has a very high R-value and adheres to all surfaces with no cracks or breaks.

It also prevents mold and mildew, since it doesn't let air or moisture through. Cellulose, on the other hand, is an ideal insulation type for attics and acoustic insulation of ceilings.
