Choosing between an MBA  and a PGDM depends on various factors, including your career goals, the specific programs you're considering, and the educational institutions offering them. Here are some key points to consider:

MBA- Master of Business Administration

Accreditation: Often offered by universities, MBAs are typically recognized as degrees. They may have more formal accreditation.
Curriculum: MBA programs usually emphasize a broader curriculum that covers various aspects of business management, including finance, marketing, operations, and strategy.
Duration: Generally, MBA programs last two years for full-time students, although there are one-year programs available as well.
Global Recognition: An MBA is widely recognized internationally, which can be beneficial if you are considering a career abroad.
Networking Opportunities: MBA programs often provide extensive networking opportunities through alumni connections and industry partnerships.
PGDM- Post Graduate Diploma in Management

Institution Type: PGDM programs are typically offered by autonomous institutions and may not always be considered a degree, depending on the country.
Flexibility and Specialization: PGDM programs can offer more flexibility and may allow for greater specialization in certain areas of management.
Duration: PGDM programs usually last one to two years, with many institutions offering a one-year intensive option.
Industry-Relevant Curriculum: PGDM courses often focus on practical knowledge and skills tailored to current industry needs, which can be beneficial for immediate job readiness.
Cost: PGDM programs can sometimes be more affordable than MBA programs, depending on the institution.
Conclusion

Career Goals: If you aim for a career in academia or a multinational corporation, an MBA might be more beneficial. If you prefer a more practical, industry-focused approach, a PGDM could be the better choice.
Institution Reputation: The reputation of the institution offering the program can significantly impact your decision. Research both MBA and PGDM programs from reputable institutions.
Networking and Alumni: Consider which program offers better networking opportunities in your desired field.
Ultimately, the "better" course will depend on your personal circumstances, career aspirations, and the specific programs you are evaluating.
