G3 more closely mimics real physics...but, and this is a very big but, the planes in G3 exhibit snappiness, especially the 3D models, because...well...that's what happens with tail-heavy 3D models. The sport models exhibit this trait also, to a lesser degree. I've flown G3 and AFPD, and I've flown the real stuff since '82. A noob will prolly like AFPD better, as there is much less inertial (kinetic energy) rotation during extreme maneuvers...almost non-existent at times. I didn't like the helium-filled feel of the sim, even sped-up, compared to G3.

G3 will make you a better pilot, AFTER you have learned the basics, because of its inherent snappiness, with the sport/3D models. Its trainer and other "beginner" models are docile enough to learn the basic skills, no problemo.

AFPD wll appeal to noobs, because of its easy, almost too easy, flight characteristics. After using G3 for a bit, and then switching to AFPD, I was able to unrealistically look like a pro with it.

Finally, it's personal preference. For whatever opinions I have (that only appeal to me), you will find those who have 180 degree, diametrically opposed viewpoints. Try both of the sims for extended periods. Buy the one that appeals to you personally, as you only have yourself to please...not anyone else.
