Mine is also a premium and I have to say I like the seats. I get no back issues or leg.
I have driven it spirited and have no issues with cornering, but there will be an advantage for the Recaro's on track.
Only think I will say about the Recaros seats is that they are black and red. Now thats fine on a Black, or white GTR, but no so sure on a blue, Orange or Grey. Feels like wearing shoes with a tracksuit, it just doesn't go in my opinion.
