Only for 2024 or maybe late 2023 cars and later (HW4). The older the car is the worse the FSD software is because the old hardware can't run the latest software.
I can't speak to FSD's quality on HW3, I never had FSD on my Model 3. I did have EAP and it worked really well on highways.
But what is your argument? newer tech will bring improved outcomes? I'm sure HW5 will be even better. But that doesn't change the fact that FSD (on HW4 vehicles of which there are tons), is really good.
