The blessing/curse of the release of a legendary ship is that it lays out a clear path to a beastly fleet. Bounty Hunter and Rebel ships so you can unlock Han's Falcon and then lawl your way to victory while your rebels unleash an obscene amount of assists and dispel absolutely everything.
Granted, BH ships are long farms, so in the meantime, all the TIEs (Imperial, First Order, Silencer, and Advanced) are good choices, as well as Biggs and the Phoenix ships.
