I can technically use either, but with VT, I have to setup a hotkey to reset my audio device. Apparently after people talk it causes a problem with VT, it's a known issue with some folks computers. It takes a seconde to reset, so I can't always respond on demand, but I can hear everything just fine (unless it's resetting and then it causes a brief pause in the audio, afterwhich I get a nice little "ping" sound and everything is fine again).
