I use both the cockpit and the custom view, depending on the car.
Cockpit view in the FOX and FO8. Custom view to remove the wheel in the MRT because it hides the dashboard, and to sit a bit higher in the BF1 because in some turns the driver's hand hides the apex or the track-out.
In tin-tops it depends on how well I know the combo. Sometimes I use the cockpit view, sometimes the wheel view.
