Both SP Jain and IIM Kozhikode are considered to be reputable management institutes in India, and they have their own unique features and advantages.

SP Jain has a fixed domain system where students have to choose a specific domain like finance or marketing in the beginning, and they cannot change it later. On the other hand, IIM Kozhikode has a flexible curriculum where students take a common first-year curriculum and then choose relevant domain-specific subjects in the second year. This allows students to explore different areas of management before committing to a specific domain.

IIM Kozhikode has the advantage of the IIM brand name, which is considered to be one of the most prestigious in India. However, SP Jain has a more diverse student body as there is no reservation policy and the average placement package is higher than IIM Kozhikode.

IIM Vishakhapatnam, while being a newer IIM, is considered to be behind both SP Jain and IIM Kozhikode in terms of reputation and placements. Ultimately, the decision of which institute to choose depends on the individual student's preferences and career goals.
