It's 2nd best. The best is an Int or lux int. An int, if it is allowed to, can kill you. An int has the firepower to nock out your shields and down to 2 bars of armor in 5 seconds flat. Fighters can rip, ints can't.
Fighters can kill caps, bombers, and bases.
Ints can kill bombers, but run into trouble with caps and cant touch bases. Fighters have a very flexible weapons loadout and they have better anti-base missiles at the sup center. Also, to stage a forward attack with sups you need 2 tele receivers. Fighters are adaptive. They can strike in multiple places at once.
