Fiberglass insulation vs. Blown insulation...which is best? - retaining wall standards

We live in Upstate New York and remodling our house a hundred years. How best to insulate exterior walls. We do not pull on the outer walls. The walls are plastered on sheetrocked, shooting. For some, we noticed that he remdloing blown insulation, but has settled in recent years. Would it be better if the walls and the use of standard isolation or in. We are, therefore, contribute to keeping the heat from the blown glass? The cost is a big problem, as we do it myself. In addition, by using a fiber insulation board slides on the interior walls with a new cast to be effective? Thank you for your help.
