Query: More thorough than Nelson's pediatrics

I referred to this book frequently throughout my pediatric residency training and invariably came away with an in-depth understanding of the pathophysiology, clinical presentation, and evidence-based treatment of a wide breadth of pediatric problems-- I wish I had time to read the whole thing! I consult Nelson's Pediatrics often as well but usually find that Rudolph's provides more complete information on etiology and more up-to-date treatment recommendations. Rudolph's is generally more thorough than Nelson's. My only unfavorable comment on Rudolph's is that the index is not as extensive as Nelson's so that one has to search somewhat longer for the relevant section. Still, I think Rudolph's Pediatrics is an essential reference for all pediatric residents and practitioners.
