Without being a stick in the mud, the Trumpeter Hornet bow is all wrong...completely losing most her curves...
I have heard this was to simply the casting process, but, if you do it full hull and are looking for 100% accuracy (or 75% for that matter), then don't tout the Trumpeter as accurate, it's worse than the BWN hull.
The best Yorktown Class Hull is, ironically, the 30+ year old Revell hull...although not 1/350, it's correct in plan, profile, and cross section at frames.
I did an article with Michael Vorrasi comparing and contrasting the BWN Yorktown Class and Trumpeter Hornet. It's located at:

Check it out... now, that being said, if you do Hornet as a waterline model, you can't see any of the aforementioned problems. The remainder of the kit is a damn good rendering of the Hornet.
