I am looking at the HWK-290 and can't help thinking I like the look of the standard edition.
If you give it an Ion Cannon and a gunner, you can pretty much be sure you'll get the ion token through.
If you use blaster turrets with a gunner, it's needing a focus token is somewhat mitigated.
It has less hull and shields than a Y-Wing, but 2 Agility. The movement dial will seal it for me as maneuvering will help with increased cost and reduced hull/shields and the range 1-2 restriction.
Maybe 2 with a tooled out B-Wing?
Even the named pilots might prove quite efficient.....
