Safer for the pilot is all the information in an understandable format...
... when it's needed. The pilot also needs to be very familiar with the systems and not confused by multiple icons and overlying graphics. The best version I can think of is one that would give the pilot a 'clear sky' version of the plane's attitude and altitude while marking terrain and weather obstacles even when the plane itself is flying in heavy clouds or fog. Virtual reality is becoming Enhanced reality with modern technologies which should make the pilot's job much easier. Let the plane worry about itself; the pilot needs to focus on actually flying. The Air France plane should never have gone down in the Atlantic if the pilots had understood their displays better. Even with iced-over airspeed sensors, GPS should have provided enough ground-speed data for the pilots to retain control and fly out of the weather. There is such a thing as information overload and that crash definitely proved the point.
