USDM wrx sti vs JDM wrx sti

I've been wanting to post this for a while and never got around to it. If you could have your choice, which would you have? I can't choose. both have great power, but the USDM has a 2.5 liter, which is a better base for power, but also adds more wieght to the car. Does anyone have slalom figures for these cars or skidpad results?

Us.
