Unpopular carpinion: Impreza WRX and Lancer Evo are better than Skyline GTR.
Most of people says that Skyline GTR is one of best JDMs ever made, but I disagree with that.
They have/had very very similar performances, they were/are very very similar looking, only the GTR was a bit angrier looking. But the Impreza and Evo won the WRC Championship, while GTR even didn't have rally car version. It only had a lot of boring and stupid modfications.
