Honestly, it depends on what other cars you have already driven. Many people who buy model 3 don’t come from higher priced luxury cars. Model 3 is better than bmw 3 series in driving, but not as good as their m3
If you enjoy the Model Y more than the M3, then you prefer it to a car that has much higher cornering performance, much higher acceleration from the 0-60 all the way to 155mph, and of course the M3 is a much rawer experience.
If you don't, that's fine, it's just that the M3 wasn't made for you.
As for the Model 3 performance, I agree.
You should compare it to a BMW X6 or 6 GT, both of which are also not sportscars but still on the sporty end of the SUV like spectrum.
If you want to compare a fun to drive Tesla with a BMW I would take the Model S and the M5, both are large comfortable saloons designed to be fast.
