Which is considered more prestigious for college admissions: the University of Wisconsin or USC?

From a pure name-prestige standpoint, USC is usually seen as having more national prestige overall, especially in selective private-school circles, high-profile media/business fields, and on college lists where private-university branding carries weight. The University of Wisconsin, usually meaning UW-Madison, is also very well respected, but its reputation tends to come through more as a top public research university than as a broadly prestige-driven brand. In other words, USC often gets the stronger immediate reaction from people thinking about exclusivity and status, while Wisconsin gets a lot of respect for academic strength, scale, and research.

USC tends to appeal to students who care about broad national visibility, a polished private-school image, and strong networks in areas like entertainment, communications, business, and parts of tech.

Wisconsin fits students who value being associated with a flagship public university that is deeply respected in academia, STEM, economics, political science, and research-heavy environments. It has a very strong national and international scholarly reputation, even if it does not always signal the same social prestige to the average person.

So if you mean everyday outside perception and label prestige, USC usually comes out ahead. If you mean serious academic respect, especially in many research-oriented or technical contexts, UW-Madison is absolutely in the same conversation and can be stronger depending on the field.
