Learner 001 - I've flown round dials to full glass. Obviously FMC's and EGPWS are light years beyond the 727 for situational awareness. But nothing is as fast for a basic instrument scan as an altimeter pointing at 12 o'clock and the VSI at 9 o'clock. Instant awareness of your altitude and sink rate.
IMO the tape display, while nice with the low and high speed buffet tapes on the airspeed, cannot compare to the rapid awareness you have with round dials and moving needles.
