I think the problems you had with the transmission on your car have left you with some bad feeling about the car. You obversely, did not do your home work before purchasing the car, like, comparing it, driving other and most important learning about the NSX
Secondly, your are comparing two different types of cars.
My advice is for you to sell the NSX...let someone else enjoy Her

"Obversely"? Just because he has some concerns, does not mean that he should sell the car. I think what the owner is looking for is some empathy, and maybe some guidance on how to fix (or workaround) some of the concerns he has, which other NSX-owners may also have.
Some general observations/conclusions:
1.) The NSX is not an Audi/BMW/Lexus which have newer luxury ameneties, added weight from sound deadening and a design that is less weight-sensitive. Arguably may be better 'designed' for high speed than the NSX, given the market demand of the Autobahn....
2.) The NSX does have wind noise - due in large part from point#1, however, ensuring that the the old seals are still good, window is in allignment and shitzu (sp?) grease are all things that are going to mitigate it.
3.) Good Tires & Allignment is necessary for a positive driving experience and helps point#2
4.) The NSX can be very fast, but it has to be 'taken advantage' of ('raped' shall we say? may not be the most sensitive word but you get the picture..)and driven well to take full advantage of. Honda's love to rev, and they have to be kept in the upper-range of the rpm to get maximum performance.... Audi's peak torque is generally towards the lower/mid so it's easier to take advantage.... The NSX, being a mid-engine car has excellent handling characteristics, which are different then what most people are used to, eg: front-engine car, and those have to be taken into consideration when comparing the two..
5.) NSX is a unique 'class' and not in the same as a Audi S4/BMW M3. Not saying one is better than the other, but they excel at slightly different applications and have pros/cons.
6.) NSX is not made for basketball players... Actually, I will complain about the height issue as well. I'm only 6"0, but with the T-TOP on I don't have as much headroom as I prefer...
Nonetheless, if you can afford it, and you like both of them but concerned about some 'quirks' I say keep both and fix some of the things that are bothersome (which you are doing..) and don't get discouraged by anyone...
As for me, I feel ya. The NSX is not God, it does not last forever, it is not super-duper fast and luxurious and it is not the best of the best of the best of all categories in automobile market.... However, with the right perspective and expectations, a little bit of education and maintenance, it can be a very enjoyable machine...
Just my 2 cents.
