Since my cousin studied in Pune and Mumbai both can answer this question better. Here is what she has to say about it. In terms of Management Studies, Mumbai can be considered as a better option than Pune. It is because Mumbai is the corporate and financial capital of India.

Now, when comparing Athena School of Management and ITM Business School, the events can be different,

• Location: Athena is located in Powai, which is mainly a corporate hub in Mumbai, while ITM is located in Kharghar which is not basically Mumbai.
• Faculty: The faculty of Athena are known to be the Top Corporate executives. ITM, on the other hand, has a faculty of academicians and several retired corporate professionals.
• Directors: The director of Athena is a former SP Jain and Wharton alumnus. Meanwhile, the dean of ITM is from Lucknow University.
• Internships: Athena provides multiple internships to students, i.e., one in each semester. In contrast, ITM only offers one.
• International Exposure: While Athena provides Two International immersions, in Singapore and Germany, and an Optional International Internship; ITM only offers One International Immersion typically for just certain specializations (International business only).
• Corporate Contact: The arriving guest faculty of Athena every week usually is a CEO or CXO. students widely take part in several ASSOCHAM or IBA or IMC Corporate Conferences, Entrepreneurship, and Startup Summits. While ITM only has visitors from certain corporate faculties and conducts in-house corporate case study competitions.
• Peer Group: Students of Athena have pursued courses in the US, UK, France, Madagascar, Bahrain, Nepal from several parts of India. In contrast, students of ITM are usually only from Navi Mumbai, North, East, and Central India.

Placement Reports: A brief highlight of the recent placement statistics at the institutes are as follows.

Based on this long list of factors, it is pretty clear that Athena is the clear winner.
