Depends all on what the fighter is meant to have as a task. For example something along the likes of a dive bomber is more focused on hit-and-runs which means it has to have high speed and doesn't need that much rotational thrusters. Also u face the enemy headon so you need strong Amour in the front and also on the rear. You See why everything is depended in the Job? Long range fighters need more fuel tankers and generators to keep on flying, while short range interceptors may only need batteries and smaller/less fuel tanks. I generally fly what is needed of me. Tho i prefer small, quick, and very maneuverable ships
