The thing about value is, it can change between a generic and a unique.
But you normally pay a premium for the unique. That premium cost doesn't seem to show here, is my only point. They seem too cheap. Hence, I feel they are a point or two under costed. This will not be game breaking, but the question was asked, and this is my analysis.
As far as I can tell, Ezra with PtL is pretty much at the top of her game, when comparing her to other 23 point ships, as is Zeb at 18 points.
