Since this thread started, I've gone from the CRJ (glass, no autothrust) to the Airbus 320, to the Gulfstream 450 and now back to the A320.
Moose is right! HUD is where it's at. You are looking right where you are aimed at, you've got more trend clues than you can possibly pay attention to, and with the EVS (FLIR) in the Gulfstream it is dang near impossible to hit anything unless you really want to.

Now they are going to upgrade the Planeview with synthetic vision, a forward PFD view of database terrain and the flight path vector. Too bad we will never see this in commercial aviation. OTOH, the G bird has the most antiquated basic systems I've flown since the DC-3!
I love the bus, but put the Gulfstream cockpit in it and make the darn throttles move. Once you become one with the HUD, you are spoiled for life!
