Which is the better university for MS in Switzerland, Eth Zurich or EPFL (Lausanne)?

Applying to other Swiss universities is not the same as applying to EPFL. There are various reasons why this is the case:

Eligibility: EPFL has varied requirements for eligibility depending on the program. For example, consecutive Master's programs require a minimum average grade of 4.5 for the whole Bachelor's degree.
Application procedure: For various programs, EPFL offers distinct application procedures. Applicants who possess a Bachelor's degree in the same field of study from a Swiss university, for instance, are required to complete the entire online application process.
International diversity: With a current ranking of 12th in the world for international professors and 16th for foreign students, EPFL is well-known for its great international diversity.
Fees for instruction: Both Swiss and foreign students at EPFL pay comparatively little in tuition.

Divergent views exist on EPFL for MS.Some people think that although EPFL might not be as well-known abroad, it has a strong reputation in Switzerland. Others counter that the EMBA programme at EPFL is well-rounded and heavily emphasizes innovation and technology management.The EPFL EMBA program's emphasis on innovation strategy and technology management appeals to certain individuals. Some counter that it might not have the comprehensive and in-depth general management approach of a course accredited internationally. While some advocate for looking at part-time EMBA possibilities, others propose using EPFL as an alternative to traditional MBA programs.

It is necessary to choose EPFL for MS in Switzerland over the University of Bern because it is the only institution with a nuclear reactor, fusion reactor, Gene/Q supercomputer, and P3 biohazard facilities, EPFL is renowned for its research, innovation, and illustrious alumni. With students apparently hailing from over 125 different nations and more than 50% of its instructors coming from other countries worldwide, EPFL is also one of the most varied institutions in Europe. For both Swiss and foreign students, EPFL charges comparatively modest tuition; for Bachelor's and Master's students, the maximum price per semester is CHF 650. 

Depending on what things mean to you, living on-campus at EPFL can be a better integrated and more convenient student experience than off-campus. On-campus housing puts you in the closest reach of academic buildings, research labs, libraries, and so on, thus lowering your commuting times and allowing you to stay pretty strongly connected to campus activity.

You'll find yourself in a vibrant multiethnic student community, which usually helps with networking, socializing, and academic collaboration. Campus life is enhanced with student events, clubs, and extracurricular activities, which build a spirit of community. 

Off-campus might be more in the way of privacy, and some of those may even be larger than on-campus spaces-a consideration against which to weigh the commute and loss of engagement with other students. Off-campus residence might provide a more favorable environment for quiet study; however, it often confines one to activities outside the campus.
