I drive both cars pretty regularly. My boss has a track edition 07 z, convertible, which is comparable to the g35 (i think?) and my good friend and one of my best customers owns an S2K.
Honestly, I think the g35/z is an old fat man's car, while the s2k is a driver's car. The torque curve on the Z makes it fun to drive... for about 10 minutes, then you're all like, I don't have to know what gear I'm in to pass on the highway/take a turn!
My point being, is that the S2000 is a stiff, driver-oriented car, that needs you to drive it.
The Z, however, doesn't need much driver participation, and is a heavy beast.
And this is from someone who loves nissan's and hates hondas. but there's always the exception.
