F-14A VS F-15A WVR, early 70's ATA combat

Recently I have been reading Osprey’s book of Irainian F-14 tomcats units in action. There is a whole chapter to why the F-14 was selected over competitiors, notibly the F-15A in weapons systems etc…

The part I don’t quite understand is when the Iranian pilots express their preference for the F-14 rather than the F-15 in WVR combat, of which Im lost:confused:

They claimed they could exploit the F-14’S airframe in more way than the F-15’s, in greater flight regimes, e.g utilising the VG wing supersonically etc…

I dont understand this as the facts are, or at least I thought, the F-15 exceeds the F-14 in nearly every physical performance goal. TWR, Turn rates, acceleration etc…also the F-15 had a more advanced HUD than the F-14 at the time. Nearly forgot about the very promblematic tomcat engines which surely would have been much harder to use than the F-15’s hightly advanced PW.

Could anyone elaborate in why the Iranian AF came to that conclusion?
