The framing structure of your house is going to be stronger if you spray the insulation into the stud wall cavity. This is because the two liquid components that the insulation is made of will become chemically bonded, and as a result they will create a rigid plastic-like material which will tie the exterior sheathing and the studs together. This will create a monolithic wall barrier that does not have voids or gaps, and as a result your house will have added protection against harmful elements.
