It has been well established that the STi beats the GTO in almost every aspect of proformance, if you doubt that just check out Edmunds.com comparison, to make matters worse the Evo stomps the STi so it would totaly OWN the GTO in a streight line and on any track. Dont get me wrong I really like the GTO but in stock form it is no thinly disguised racecar like the Evo, but for everyday driving the GTO is smoother quiter and more comfortable. However it would not take much to modify a GTO to outrun either one of them. LS2s hadle supercharging and NOS quite well in modarate doses (enough to catch the smaller cars and then some) and if you stiffen up and camber the suspension you might not catch them in the corners but you will not loose any real ground. Good luck.
