That's what I kind of figured too but isn't 3.5 stated and 3.2 real world performance about the same as what Model 3 performance got? P100D can do 2.4 sec 0-60. Porsche should make its $150K EV more or less perform like that (I thought it benchmarked the Model S). Either Porsche is not able or not willing to make it that way. It's probable some of both.
Neutral is always better. You will have more options to tune the chassis to whatever is best to suit your likes. Oversteering forced upon you is never desirable not to mention it can be dangerous lot of times. In the early days 911 got killed, both figuratively and literally, by Ferrari on race tracks. Many begged Porsche to go mid-engine. Porsche never wanted to do that not for engineering reasons but that would not be the 911 anymore. It's only saved later by electronic stability and traction controls. Although don't think YOU are driving the car if you are such a purist.
Driving on the track for most of us is about fun, not competition. As such, 'better's is subjective. I had substantial experience with both 911 and Cayman and as such, I'd say 911 is more exciting(i.e. scary), while Cayman gives you more optionality in how to drive it. As one develops as a driver, 911 at first seems more challenging, which would also make it more fun, which is also what I've seen expereinced journalists talk about. BUt, as an owner, with plenty of seat time, there comes the time, where 911 doesn't feel challenging anymore, but limiting. I.e. you need to drive it on the rear axle, and manage it carefully to be safe, and Cayman gives you more options to play with.
But again, better is very subjective to what do you want out of the car, and where on driver development journey you are. For people that find 911 mass distribution challenges ridiculous, rather than charming, Cayman will always be better choice. For those that think 911 is charming, it's a valid point, and only if they spend exorbitant amount of time on the track, there may be a time when once you understand it well, and it becomes limiting and not charming...
I've got about 10 years with PCA, black for majority of that time.
For anything other than the track, I love my Tesla...
