I just went through the same exercise recently and landed on a 2017 S with Sport Chrono and am happy with the purchase for these reasons.
-Performance, I plan to autocross and track it.
-Styling (subjective)
-Interior(subjective)
-Driveability around town
-Newer car with a significant amount of warranty left. (this is a big deal for most)
Most will say the 718 is a better car in pretty much all areas but sound. With that said, I have heard nothing but good things about the 981 cars.
Personally I love torque.... Another thing to keep in mind is the 981 cars need to be wound out in order to make power, and with that, you will be making that glorious noise any time you want that forward thrust... that is good and bad. You will be bringing attention to yourself every time you want the car to have some fun. I drive a winding country road several days a week when going to work. There are enough houses that over a few weeks of doing that, some may be calling the police and soon enough it could turn into a problem.
The 718 gives you that fun thrust almost always with little drama from 2000-4000 rpm. So just leaving a light, or after turning onto a street with a bit of right pedal and its a hoot without bringing attention to yourself. Turn off the PSE and there is even less drama. You can still let her rip up to 7500 RPM any time its appropriate, but its not needed to have fun in the 718.
Im not discounting the sweet song of the 981 cars, its emotion stirring for sure and if that is more import, find a good car and go for it! For me, the other benefits outweighed the sound.
