E-Wing is 3/3/2/3 with barrel roll and Evade - and most notably has a much better upgrade bar - it equips Torpedoes in addition to System and Astromech slots (with the System slot notoriously raising the cost of ships over expected) AND the shields + astro make it a great position for Regen, taking synergy into account.
Also I'm sure everyone will tell you E-Wings are like 2-3 points overcosted in the first place too.
