Well you guys have to give facts here why do you think it is better.
Let tell you one thing from the starting line an Evo will be faster due to its lighter weight which is about 250kgs if not more lighter then the GTR but at the top end the GTR would catch up if not pass it due to it having 600cc and 2 extra cylinders and this is where it matters but on the track the GTR has been beaten number of times as shown on some of the BMI video Magzines.
But these are two different animals and different class of cars which are rearly compared. The actual competition to GTR is the Fire breathing Supra which is capable of producing 1520whp and tested on a Dyno myself and FLi had discussed this over the phone sometime back, that is another story :). Evo is always compared to its rally counterpart the Subaru WRX STI. Which is closer in weight and characteristics. Being a Evo owner and having driven and worked on a GTR I say these two have different advantages.
