Which is considered more prestigious for an undergraduate degree: University of Michigan or University of Edinburgh?

Neither one is universally “more prestigious” in every setting. In the U.S., University of Michigan usually carries more immediate weight for undergraduate study, especially with employers, graduate programs, and people familiar with top American public universities. Internationally, especially in the UK and parts of Europe, University of Edinburgh has very strong name recognition and can feel just as prestigious, sometimes more so because of its long history and global visibility.

Michigan tends to stand out most for students who want a highly regarded U.S. undergraduate experience with broad strength across disciplines, big research opportunities, and a powerful alumni network in American industries.

Edinburgh often appeals more to students who want a globally recognized university with a classic UK academic structure and a strong international profile. It has a respected reputation in humanities, social sciences, informatics, and sciences, and its name carries particular weight in the UK and abroad.

If your question is purely about broad brand value in the American undergraduate job and grad school market, Michigan probably has the edge. If you expect to build your career in the UK or in more international settings, Edinburgh is at least comparable in prestige and may even be the more recognizable name depending on the audience.
