And if you compare videos of F-4s with wing slats making a tight, 180 degree turn (see 4:25 above) compared to F-15s doing the same maneuver, you will note that they both average seven to eight seconds to complete the turn, even though the latter is purportedly more maneuverable.

This statement is highly misleading. Any aircraft (F-4, F-15, Su-27, B-1, 747, whatever) will take exactly the same amount of time to make the same turn at a given G-loading. What differentiates “more maneuverable” aircraft from others is the amount of airspeed left at the end of the sustained turn, which impossible to compare from the video. The statement also omits any mention of instantaneous turn rates and high AoA behavior, both critical for close-in ACM performance. Lastly, it’s clear from the video that the F-4’s are using afterburner to add energy. This is not sustainable for any great length of time due to high fuel consumption. A more recent fighter with higher dry thrust can maintain a turn without using afterburner.
