Thrawn with VSDs seems as good as Jerry to me, if not better. You can probably get 1or 2 turn of getting your fleet into position before combat starts so you don’t need Thrawn, then 3 dials for turns 3-5. And you don’t have to take a damage.
An argument could be made for cost issues of course.
i ran 3 VSDs with Thrawn. Need extra manoeuvre 3 times per ship is 9 damage. Thrawn seems worth that to me for 10 points.
