In the real world they very much are similar on most road courses. However, in my computing simulation process they appear to be 22 seconds apart on Germany's north loop both in standard form and 18 seconds apart in Weissach form

https://docs.google.com/spreadsheets/d/1mc-JJgfFrlYYFGuv3ohleC_rh7k8G3yp73DMb6UpCD8/edit?usp=sharing

GT3 RS: ((20600m/(300km/h/(321m*0.3048m))x(1497kg/589hp)/1.31g)x0.0095 x 0.700 to 0.725

GT2 RS: ((20600m/(300km/h/(301m*0.3048m))x(1523kg/775hp)/1.31g)x0.0095 x 0.925 to 0.950

A Weissach-equipped GT3 RS is capable of producing a maximum of 841 hp on Germany's north loop circuit, while an equivalent contemporary GT2 RS is capable of "only" 837 hp. Sorry GT2 fans, but the GT3 is the real track star.

I think with the same amount of power the GT3 RS would be faster on track.

I disagree.
If you just put turbo on this car and increase power to 700 or may be even 800 hp it won't get any faster on the track, probably would be slower.
The original power/chassis balance would ruined and the car would be very hard to handle while cornering.

I mean the GT2 RS is only faster because it has more power.
The GT3 RS is faster at 18 and 36 meter slalom, has better braking performance, is lighter, and it also has better lateral acceleration.

Well, if so, yes. GT3RS is definitely faster in corners.
