TISS - Tata Institute of Social Sciences, Mumbai

Both are not good. Although TISS started MA in social Entrepreneurship and TISS is a reputed institute in India for social work, it has not got so much reputation for its social Entrepreneurship. same is case with its LLM program and in other hand I don't think ISB offers social Entrepreneurship course. A better suggestion for you to join a social sector organisation and after 2 years experience, enroll in MBA Social Entrepreneurship part time program of NMIMS as it offers lot of scope from presentation skills to case study, faculty from industry and from different sector. scan my blog blog.simplycareer.net for more details including review of the program as well as comparison with other institutes.
