Not significant tbh
You don’t need to manouver much and since you do get an aesa radar you can require lock very quickly
EFT will win if the joust is close though, unless C GE decides to MCM, which brings the fight more in its favor (whether you like it or not MCM is a tactic)
How many small?
J-10C currently uses 72 large caliber CMs so you’d need a solid (larger) amount of normal or smaller caliber CMs to match that or be better
Pls double check source’s reliability too
Some patriotic players have a habit of falsifying info and Chinese players from my experience can be more patriotic than most (comparable to US/RU players tbh)
Argument is probably long over but I wanted to contribute my two cents anyway:
F-15C GE is arguably worse than the future F-15EX which is a budget AESA-Typhoon on account of having less radar gimbal limits, no IRST (unless taking Legion pod which still produces drag and weight), no MAWS, and having similar climb-rate and acceleration to the Typhoon but worse maneuverability.
F-15C GE can remain at 14.3 while being worse than the F-15EX which can be introduced at 14.7 but that would still be worse than the AESA-Typhoon at the same battle-rating.
