AFPD is a ton better than G2! Now for the question of "can I see the plane and ground at the same time while at 20 ft. altitude?".... that all depends.... 20' right over your head or 20' while 50' out from you?

Of course no simulator with only one screen is going to give you the peripheral field of view that you have while flying in real life. But I do say AFPD is worth having. Besides, why fly 3 mistakes high when you have unlimited supply of (simulated) airplanes???
