I agree with KP. However, I liked Rosai better because it was like reading a story book. Also, all of the chapters are written similarly (except heme, liver, kidney and neuro) because Rosai wrote them all personally. I liked that continuity. Also I think Rosai offers a wider differential diagnosis and points out more obscure variants.
Sternberg is more concise and starts from the beginning. It assumes you know nothing, which can be good. I read Rosai first so maybe Sternberg seemed boring for that reason.
I would recommend that you find someone that has the book. Read the chapter on pulmonary OR breast in both, and see which one you like better. You really cannot go wrong. The important thing is to actually read them. They should be marked up, have papers sticking out of them and tattered by the time you get to 2nd year. Get a new version too. It is embarrassing to read an old version and make a diagnosis of "midline lethal granuloma" when you are sign out with an attending.
