Well, I'll put it this way; Fill the stud frames with regular building insulation and it's very good... fill the air gap as well (not tight!) and it's a 'little' better.

Depends on your budget and how much you are willing to spend on small increases in quality. As in Audio Gear, quality increases of 10% usually require a logarithmic increase in budget.
