You are right there are two Heritage studies approximately 3 years apart. The later study dated May 14, 2019 basically reflect the same results compared to the earlier study.
The conversation was about maneuverability and not sensor fusion so that particular chart wan't included. Clearly the F-35 is miles ahead pertaining to situational awareness.
The F-35 starved all other improvement project for every other aircraft in the USA inventory .
Means many comparison is like saying that your 5 starved, malnutrition horse has inferior performance compared to the single well kept one.
So, the sensor, avionics and all related area (including responsiveness and example) simply related to the fact the F-35 made it impossible to improve the other platforms.
