My penny and a half: In FSX, I'll take whatever the developer offers. Since Carenado models mostly 70's and early 80's aircraft (or has), I think I know what to expect. I haven't checked to see what it means, but the Commander has an option for panel changes.
In the real world, this very infrequent flyer will take glass if I can get it just for the wealth of information on the MFD. Traffic information and airborne weather, and airport data especially. The trick is to keep it all in context and don't get obsessed on it - the V in VFR means Visual - look outside.
