What year is your GT-R that you are selling, how long you've owned it, any mods, and why you are selling, if you don't mind sharing? As for a 911 or Evora, I won't get into the whole Porsche thing, because I've never owned one, but also due to never really having Porsches appeal to me. There is no disputing their performance and handling, but it has never been a car I've spent much time in researching because I had to have one. Now, if I somehow inherited a 911 Turbo S or came across a deal on one that I just couldn't pass up, I'm sure I'd be loving it.
As for a Lotus Evora, I did briefly own a '17 Evora 400, and it was a very nice sports car, in fact, I should have held onto it. It certainly wasn't anywhere near the quickest or fastest of cars I've owned, but it handled like a dream, I loved it's pseudo exotic looks, and like the GT-R, a car you just didn't see on the streets very often. I've seen their latest model, the Emira, and feel it is a very sharp looking sports car. But going from a car such as the GT-R, which can hit 0-60 in less than three seconds and the quarter in 11 seconds flat, and a top speed of over 190 mph, I'd personally be disappointed going from that to the Evora's acceleration of four tics or so 0-60 and the quarter in 12 and a half tics. Top end I believe the Evora could eventually reach up to 180 mph. But before anyone has an aneurysm and blasts me to basing my personal impressions on acceleration data alone, and instead enjoying the sublime handling of a car like the Emira, I say, if that floats your boat, more power to you. It's whatever you prefer. Different strokes for different folks.
