IMO, SN95s are more fun to drive vs the s197 3V cars. This isn't to say they're better/faster, but they certainly are more fun to drive. My 97 Cobra is a flaming shitbox, but it's more fun to drive than my 06 3V.
SN95 cars are lighter as well, smaller, more glass, etc. I can see myself getting another SN95 in excellent shape.
