Can you compare the writing styles of Saraswati Gangadhar and Annasaheb Dabholkar based on the preface?

The preface, presented in Chapter 0, provides very limited information for a detailed comparison of the writing styles of Saraswati Gangadhar and Annasaheb Dabholkar. The text mentions that both authors wrote Guru biographies, but it does not describe Gangadhar's style, other than noting his work is famous and detailed. For Annasaheb Dabholkar, the text only offers a point of contrast with another author, Shri Dasganu Maharaj. It states that Dasganu Maharaj often depicted the pitiable state of the country in his works, but as Chapter 0 notes, "Shri Annasaheb did not involve himself in these matters at all."
