Much easy to me fly analog horizon with no APs than EFIS (very sensitive), if you have a chance try it to fly IFR conditions with no APs, with EFIS equipment, you will have a lot of fun. After that emergency CHC start to train crews in the sim with that condition
But not too hard to fly the EFIS AP out if you slow down to 120 knots, especially if you have selected the AP off so you know its coming.
I still see no real reason for a ditching here.
