Personally, I find myself sticking with programs like Ventrilo or TeamSpeak to run my voice chat. Even in Lord of the Rings Online, I find myself turning off the IVC to use TeamSpeak with my kinship. So the important question here is: What do you prefer? Does integrated voice chat cause your game to lag, or any other performance problems? Do you just prefer Vent or TS (or Skype, or Xfire, etc) because you're used to it from before it became integrated? Let us know!
