The E-ray while fast us not the same kind of car. The NC1 is closer to the Porsche and Ferrari than to the E-ray. The E-ray has a front motor that drives both wheels . It cannot vector steer. It is not sophisticated in the same way as the NC1, Porsche 918, and Ferrari.
Having said that, the 2005 you have is the last year NSX that one would say is a drivers car. If you are just thinking about resale value, then better not put a lot of miles on the car.
From my perspective I would not get rid of my 2017 and go backward to an earlier NSX. I had a 91 for 5 years and my 2001 NSX-T for 14 years. They were both fun. I love the NC1. It is a joy to drive and is so much more car then my earlier cars. But I like technology and want a car that is modern.
My 2001 was supercharged, had headers and exhaust. I had the Honda Navigation pod, special flywheel and clutch, brakes and Coilovers, and everything looked new. It was a great car. Even if I had a garage for my 2001NSX, I would have still sold it.
I would not worry too much about resale values. Both cars will hold their value. Getting rich is not in the cards for either car. I would focus more on what you enjoy driving. Keep in mind that the 2005 NSX is now 18 years old. Parts are going to be an issue.
