I fly 100% on the GPS.
An IFR panel mount unit is always (unless doing a local bimble along the coast) programmed with the route, and when flying VFR I also have the real VFR printed chart running on another GPS (a tablet computer) so I can see airspace etc.
I would not fly without GPS. Too easy to make a mistake and end up busting CAS, etc. Flying should be enjoyable, not full of worry about where exactly one is.
