I have to admit; sometimes I derive a lot of pleasure from debating with my friends about which car possesses better performance aspects. In the end, I think that the "better car" depends on the person's taste. I am a track enthusiast and I care more about cornering ability than I do 0-60. This is why I drive an S2000 instead of a 350Z. Being a track enthusiast I thoroughly believe that a car's true potential is unleashed depending on the experience of the driver.
In the end, I don't think it really matters as long as the owner is happy with his/her decision.
Just my two cents.
