Depends on the nature of the battle. In a straight confrontation, NORA is much better armed and with Snow at their forefront I can't exactly see them losing any particular battles.
But therein lies the fact that the Turks are a covert unit with access to a lot of staggeringly powerful technological advantages. The forefront of these advantages being aircraft, which would pretty much single handedly eliminate every NORA operative that wasn't Snow. The guy has pretty much already proven that missiles mean nothing in FFXIII.
