Personally I would never give up glass cockpit - it gives me superior situational awareness and I can actually spend more time thinking about the big picture (weather, fuel, alternates, etc.). But it is just a tool and can be easily abused like anything else.
I am presently in the beginning stage of building a Thatcher CX4 as a time building rental for young pilots between their PPL and CPL.
Here is my choice for the instrument panel.
Dynon Avionics - SkyView Displays
Once they have mastered airplane handling skills I want them to have the most modern situational aids available.
In my opinion it is like a gun.
I would rather have a gun I don't need than need a gun I don't have.
