What is actually the difference in student experience between a world famous university and others? What would be the practical difference in terms of quality, experience, and future prospect if a student studies at a 4-year undergraduate degree in a world famous university like Harvard compared to a top university in a developing country, like, for example, in an Indian IIT?

Suppose the syllabus contents are the same and and the major is highly technical like Electrical Engineering. My question is not limited to Electrical Engineering, any technical subject will do.

Future prospect means: researcher (academic/industry), entrepreneur, professional, anything that gives him money or/and fame.

The aim of this question is not to understand the career prospect of a student who graduates from a world famous university. The goal is to understand the academic atmosphere or academic culture and academic productivity of the university. My question talks about Undergraduate for a reason. Graduate and PhD degrees are mostly related to research. So, it is natural that a world famous university will offer more scholarships, source more funding for research and deal with more advanced technologies than that of a university in the developing world. 

To my understanding the teaching methods, psychology of people, and goal of higher education play big roles there. For example, in the developing world a degree doesn't always mean that you learned something useful nor does a degree doesn't secure one's career because of various socioeconomic realities. 

Given that the syllabus is the same, instructors may need restrict themselves into theoretical discussions only or conduct lesser labs because of the lack of sufficient instruments because of budgetary constraints. Moreover, in developed world teaching methods and syllabuses are also subject to continuous research and improvement which is not always true in the developing world. 

Salary of professors and their living condition is also a factor in the developing world. Above all, the feeling of not being a part of developed world plays a big role in their motivation.
Even if you could learn exactly the same thing in both places (you can't), another difference is your peers. If you are surrounded by people who are smarter and more driven you'll be more likely to raise your own standards. The best project in the class at Leading University will be different from the best project at Third Tier U.

Also, if you attend school with people who are likely to get great jobs, you'll have contacts with people who have great jobs, increasing your own opportunities.
