I understand what you’re saying. Personal bias is hard to self-monitor.
But on many objective measures Tesla’s touchscreen is worlds apart from any of car touchscreen. It is iPad-like responsiveness as far as touch recognition and refresh rate.
I always said I would never want a GPS/Nav system in a car, because what would be the point?! Low quality maps, no decent POI, no decent user input for querying POI, bad routing, no pinch-to-zoom in a complicated intersection, slow to load, etc.
My wife’s Mercedes has Nav and we used it exactly once.
By contrast I always use Nav in the Tesla because I can map to Work or Home in two taps in 1 second, boom, the map routes and zooms to show the overview and I have a traffic aware route with an accurate ETA.
The live traffic lets me see if traffic is slowing ahead on the highway. Often times I will slow down to the speed limit when approaching a red zone ahead on the highway. Someone behind will swerve around me and accelerate hard just to come to a screeching halt around the bend. Craziness.
I think “build quality” and “materials quality” is way more subjective and harder to quantify. But the screen interface is on a different level.
