I'd say Guri, most likely. The Segnor's Loop maneuver with his free Focus at range 1, Autothrusters and Advanced Sensors (assuming Virago, of course) is such a potent combination for range 1 survivability from fat turrets, Kavils or a range 1 face-blast from another ship that it's silly. Advanced Sensors into Evade, S-loop behind / into the opponent's grille, take the Focus, and blast away.
As a side note, munitions are also excellent for Guri. Advanced Proton Torpedoes, I think, have found a home. Advanced Sensor Target Lock, get behind them with an S-Loop (or in their face with a Boost) and unleash a volley from a weapon that automatically turns three blanks into Focus. You're almost guaranteed five dice of damage. Saving this for the end-game is huge if you can manage it.
