How do the biographies of Sai Baba written by Dasganu Maharaj differ from the work of Annasaheb Dabholkar, as described in the Preface?

Based on the information in the Preface, the biographies of Sai Baba written by Shri Dasganu Maharaj differ from Shri Annasaheb Dabholkar's work in both scope and content. As noted in chunk 11 of Chapter 0, Dasganu Maharaj's two biographies are considered very short, one having 509 verses and the other 497. In contrast, Annasaheb's work is implied to be more extensive. A key thematic difference, also highlighted in chunk 11 of Chapter 0, is that Dasganu Maharaj beautifully depicted the pitiable state of the country and its causes in his writings, a subject that Shri Annasaheb did not involve himself in at all.
