Surely not?
The Imperial blasters have a hit rate of about 5 to 10% against the Falcon, as opposed to the about 100% of Starfleet phasers when firing at similarly sized ships or craft. Against agile fighters, Imperial blaster hit rate is a flat zero. In contrast, the fighters in "Preemptive Strike" and "Sacrifice of Angels" never managed to dodge a single Cardassian phaser beam.
The B5 plasma bolts have good targeting against capital ships, but then again, B5 capital ships move like molasses. It's extremely seldom that a hit would connect with a fightercraft like Starfury, though. Earthforce beam guns are clumsy affairs that again only hit capital ships. Only Minbari beams seem to be effective against fightercraft, and there nowhere near 100% in accuracy.
It may boil down to firing discipline in the end: the Feds only take the sure shots, while the Imperials consider volume of fire more important than actual hits (which it may be, if the objective is to make a fighter abort its attack run). Klingons may strike a happy medium, their "machine gun" BoP disruptors pumping out a lot of fire but only hitting about 50% of the time. But the occasion where the mirror Defiant evades the mirror Klingon disruptor bolts is an isolated one: in "our" universe, nothing comparable ever happened. Starfleet guns and torps scored perfect hits in the similar battle between "our" Defiant and the Lakota in "Paradise Lost".
