It's pretty simple: if you are low to the ground, the quickest way out of VRS is the Vuichard. Do that. There is no question about it. If you don't recognize it fairly quickly, neither method may help you. If it happens at altitude, do whichever one you want. And if you find yourself plummeting to earth in full on VRS because you fly around with your head up your a**, apparently pushing the cyclic forward is the only thing that works because reasons and I hope it works out for you in time.
