When I was “shopping” for a Instrument Rating, a few schools really pushed that the G1000 is the way to go (and charged accordingly) as “it’s glass, like what the airlines have”. I asked if I could fly a mixture of G1000 and conventional instruments on the C172, before transitioning onto the Barron which had the same avionics the Dinosaurs used millions of years ago. Worked well in my mind, as I soon after flew a mixed fleet with Glass and conventional Instruments.
