Can you provide a detailed comparison of the dialogue between Krishna and Arjuna in the Bharata versus the one between Krishna and Uddhava, explaining why the latter is considered 'better'?

The source material from Chapter 18 states that the dialogue between Krishna and Uddhava is 'better' than the one between Krishna and Arjuna in the Bharata, but it does not provide a detailed comparison or elaborate on the reasons for this preference. The text simply presents this assertion while praising the Uddhava Gita as a 'divinely inspired book' containing the 'loving speech of Nath.' The primary focus of the chapter is on Sai Baba's practice of having devotees read these sacred texts, rather than on providing a comparative theological analysis of them.
