[Star Wars Legends] What was the greatest starfighter of the galactic civil war? What topped it?

Was it really the X-wing? Or is the question to dependent on context to have a definite answer?

This question is entirely dependent on context.

The X-Wing is by far the most notable of the Alliance Starfighter Command and is probably the best all round Starfighter but while the X-Wing performs well at both bomber and fighter roles, it excels at neither. The A-Wing, with its incredible speed and traversable laser cannons, is by far the superior dogfighter. The Y-Wing meanwhile carries a heavier bomber payload and excels at fulfilling the dedicated bomber role. Unfortunately they are slow and susceptible to anti-Starfighter systems. For this reason the B-Wing was developed, a fighter both capable of carrying a large payload and evading incoming fire, making them ideal for tackling Imperial capital ships.

Where the X-Wing out performs all others is in its flexibility. Alliance doctrine called on the use of hit and run operations against Imperial convoys and other targets. X-Wings were both hyperspace capable meaning the could act independently without capital ship support and carried a big enough payload to deal with Imperial escort vessels (at least until the introduction of escort vessels such as the Lancer-class frigate). In this role the X-Wing performed above expectations (as evidenced by the Empire's need to develop ships capable of countering any fighter attacks).
