I rather enjoy Legacy, but Krayt is easily the best part of it. Him being such a clear anti-luke skywalker adds a lot. Plus the rule of one is cooler than the rule of two. It might help that he's actually a prexisting character so there's more impact to it. And that he's tied to the movie cast.
Its a shame that only talon gets constant art. Not that i dislike her.
And i would say Legacy was stronger than a lot of the others, such as legacy 2, dark empire and about half of tales of the jedi. And that 2013 star wars book.
