Hey ish
I actually went the other way by going 99 wrx to a 32 gtr lol. To me i personally think the wrx is a great everyday car and stock engine and turbo can handle quite alot without needing any supporting mods, i ran 17-18 psi everyday on stock turbo and cooler for a year and it was great. Going to a GTR on the other hand i feel its more of a track car and its abit harsh for everyday driving but performance and power feels more solid in the rb then the ej.
Handling i reckon both to their own, but to note the wrx does understeer quite alot. Just go test drive a good example of a wrx and see what you feel.
hope that helps
