I'm not sure where he was going, either, but he did mention those two radar systems by name, so that was my starting point.
Yes, the AWG-9 was probably superior to the first-generation AN/APG-63 the F-15A had; it cetainly had superior range (at least double that of the -63), but I don't know if it had better look-down/shoot-down capability (for which the -63 was designed).
The later AN/APG-63(V)3 AESA radar, as fitted to late-model F-15C MSIP's, actually has many parts in common with the AN/APG-73 and AN/APG-79, as fitted to the F-18C and F-18E/F/G, respectively.
I would make the folowing modification to my comments in the light of your reply....because the two aircraft have different roles, they have different radar capabilities. What you are saying about "look down, shoot down capability does hold true when analysing the F-14 capability. They were not good at engaging from a superior height. Tomcats preferred to shoot from below, to avoid sea clutter effects on their radars. Shooting "down" had a significant downgrading effect on the efficiency of the system
I found this general link about the F-15, which people might find interesting
