OP, thanks for your thoughts and interesting observations.
As a Porsche owner, including a 911 that I just got rid of, and a Porsche fan for half of forever, the brand is an interesting one. Because there are SO MANY models (I think that at it's peak, there were 21 different variants of 991 series you could buy, and that's before options!) and the car's extensive history, that it attracts a very wide spectrum of buyers. People buy Porsches and 911's for a multitude of reasons. To that end, there are many things people will appreciate about them. What it says about them, how it looks in the garage, the racing, the performance, the craftsmanship, the individuality, the group activities, the engineering, etc. And all of that will influence how you view the car when you no longer own one.
I owned my LRAWD model 3 for a little over a year and now it's been replaced by a Performance. And to me, I feel like owning the Tesla has made me want to drive the 911 less....but when I do drive it, I appreciate the 911 for what it is even more. And even shaped my decision to get rid of it in favor of another. I'll elaborate. Hopefully I don't lose you.
911's have spanned so many years, and there are so many different flavors even in one generation, that you can have two cars that feel COMPLETELY different, and offer much different sensations, even though they are very, very similar. And when you start going into the back catalog, each generation feels subtly different to the next. Case in point, the outgoing generation, the 991.2, featured a model called the Carrera T. This car was, obstensibly, not much different than a base Carrera 2. Same engine. Same brakes. Same body. Same wheel sizes. And yet...they feel very different. The T's suspension is fettled differently, it's got different gearing, less sound deadening, slightly different engine tuning. It all added up to a much different feeling car.
All of this is a long way of saying, there are many different expectations to have of a 911, and many different experiences offered by them. Get that combination wrong, and you might end up with your expectations unfulfilled. Get it right, and they can be exceeded mightily.
Back to the Tesla. For me, the Model 3 simply is an amazing daily driver. The visibility, the quick steering, the overall performance and, most crucially, the pin-point accuracy at which you can raise and lower your speed can't be beat on a day to day basis. As I said, I used to take the 911 out when I didn't have anywhere important to go, plus some pleasure rides. Most of those in the former category were replaced by the Tesla, because it is so enjoyable to drive on mundane drives. The precision at which you can use it brings a special joy to it's own. Being able to zip past traffic, speed up and stop on a dime, it does bring joy to me for some truly boring drives, like dropping the kids off at karate. To me, the Tesla is unmatched in this category. You can actually ENJOY commuting, runs to the grocery store, etc. Other EV's have this to a certain extent, but there is some magic in the Tesla's combination of light weight (for an EV) responsiveness and speed, and quickness of response that's yet to be matched by another EV. I drove an ETron - fabulous car, feels slow and ponderous. I drove a Taycan Turbo. Wicked fast, but again, feels heavy. Responses feel muted. Feels like a sedan, not a sports car.
What the Tesla doesn't do, to me, is replace the 911 on those journeys where the ONLY reason I am going out is to drive, and to feel the road. To be connected to the machine and to feel it reacting to the road. Feel it flowing with the pavement. Feel the precision of the components beneath you. If you start looking for that, the Tesla falls flat, quickly. The steering offers zero feedback. The seats have almost zero lateral bolstering. The suspension, good up to 6 or 7/10ths and about 80 MPH, starts to lose composure quickly above that. There's no mechanical feedback to indicate speed beyond the wind noise. No "reward" for increasing your speed beyond tire squeal. That's why the 911 felt even more special when I drove it for those reasons.
The other thing I appreciate in my 911 is the craftsmanship, the build quality. The quality of the interior components are worlds better than the Model 3. Something as simple as the side of the center tunnel shows this. In the Model 3 it's pretty flimsy and insubstantial. The 911 has layers of components making up the structure. There is an engineering elegance to it. And, IMO, this becomes more and more apparent the older you go in the 911 catalog.
I never used my 911 as a daily. You could, as many have, but to me it's frustrating to do so. Too much feedback, would get irritating to me on my long commute. Conversely, the Model 3 has made my commute as almost effortless as can be. I really ENJOY driving it to and from work. It's very satisfying.
I had been looking to get rid of my early 991.1 for about a year now. IMO, as the first 911 with electric power steering, they got that wrong. It's not right for the car and robs it of a lot of the feel that you buy a 911 for. Likewise, the manual transmission is incredibly frustrating as the gearing is terrible to use in the US. 2nd gear is good for 72 MPH at redline, and that's not much more where peak power is (7,600 vs. 7,200 RPM). Peak torque is over 5,000 RPM. During ordinary driving, you don't ever hit peak torque except in first, and maybe second, when wringing it out. The 991.2's turbo engine helps this a bit. But I wanted a more raw and visceral machine, so I traded in my 991.1 and will be going to something different when the market cools. Maybe a 997.2 Turbo, or a 991.2 Carrera T. Or a 2016 991.1 GTS with a PDK. The cars with a little more verve.
In the meantime, I will enjoy driving my Model 3. I'll celebrate it for what it is, and not lament what it isn't. It's not a Porsche, not even a Taycan. And that's no bad thing....
