I'm a die-hard MT guy. I have this sticker in my window:
If I was buying a Porsche (I'm not) and knew that the PDK tranny allowed for faster acceleration (it does), I'd still buy the stick. I don't care how good the PDK tranny is.
I like my MT Impreza, but will admit that the clutch's catch point is too high, which required some getting used to.
