The biggest thing that Tesla got right besides the acceleration is the value-add features like Sentry mode, the tight integration with the phone, the things like Walk-away locking (although I would very much prefer it lock closer to my car because it's about 40-60 ft away when it locks and it makes me nervous).
The build quality is cheaper, the sound system sucks, and I generally despise how many things are tied to the screen. I want buttons and knobs for the air system, to have to hunt for that on the screen is very dangerous, I hate it.
The Porsche feels more luxurious but it's mindblowing how they get so many things wrong. The dashboard is much too complicated with a lot of redundant buttons. Something as simple as there's no place to put my phone, there's only extremely awkward locations that cause my phone to fly around the car when I go around any turn, which is so dumb in 2022. The backup camera has way too narrow field of view, I've almost backed into 2 cars in parking lots, something the Tesla got right. At least they have Apple Carplay, but activating it is extremely annoying.
I also have BMWs before (X3 and X6) and overall my favorite car of all time is the X6.
