Why is the PDF version so highly sought after?
A word of caution: The "best" PDF is a legal, paid download from the ARRL or a licensed reseller. Free versions found on random file-sharing sites often lack diagrams, contain OCR errors, or are missing the answer keys for the self-tests.
Electronics is a visual subject. You cannot see electrons flowing, so you need good diagrams. The "best" aspect of this book is the quality of its schematics and illustrations. They are clean, distinct, and standard—which is crucial when learning how to read schematics for real-world applications.
