Can't the number advantage help the GE?
TIE Fighters are hugely below TIE Interceptors, which are on par with A-Wings of the Rebel Alliance, which are of similar tier (but totally different balance of aspects) as the classic X-Wings...
Then you have the XJ3 X-Wings, who are on a new level to classic X-Wings, and StealthX is even better.
Is that enough for one XJ3 X-Wing to take out 2 TIE/LN's?
