I would say Squadrons ends up kinda midway between movie-performance and X-Wing series performance, because Squadrons is *very* much a modern reboot of the X-Wing series. The big change in Squadrons is that TIEs get the hull repair feature, which goes an *enormous* way towards levelling things versus hyped-up Rebel shields. In the old model, all damage to a TIE was permanent, whereas shield damage to a Rebel fighter could be quickly regenerated.
Note that even in Squadrons TIE guns are faster-firing than X-Wing guns, but only the Interceptor actually has rapid-fire model guns, which is backwards to what we see in the movies.
If they were true to the movies, the TIE Fighter would have two rapid-fire light cannons with auto-tracking and a short burst of 4-6 shots from those guns would shred an X-Wing, shield and all. The X-Wing would have four slow-firing but very hard-hitting heavy cannons where a single hit would cripple a TIE and two hits would outright vaporize it, but overall they are poorly selected weapons for fighter-to-fighter combat and really only show their strength when X-Wings are attacking bigger ships and can cause SERIOUS hull damage with strafing runs. The TIE Interceptor would be intermediate, with four medium impact, medium rate of fire cannons coupled to extreme maneuverability. The A-Wing would be as fast and maneuverable as the Interceptor while carrying two rapid-fire, auto-tracking guns with a *frighteningly* wide field of fire; shields make it a little less vulnerable than TIEs, and overall it is the most lethal dogfighter in the GFFA.
