Is University of Illinois Urbana-Champaign or USC easier to get into for undergraduate admissions?

USC is harder to get into overall for undergraduate admission. Across the full university, USC is typically viewed as more selective, and a more nationally concentrated applicant pool. UIUC is absolutely competitive, but at the overall university level it is usually less selective than USC.

One concrete difference is how admissions work across the institution. USC’s applicant pool is filtered through a private-university process where many students are applying specifically because of its national reputation, Los Angeles location, and strong preprofessional programs, which pushes selectivity up across most schools. UIUC, while highly respected, also serves a major public flagship role and enrolls a much larger undergraduate population.

Another important distinction is that UIUC’s selectivity varies a lot by program. Some UIUC majors, especially in engineering, computer science, and business, can be extremely hard to enter and may rival or exceed USC in difficulty. But since you asked about overall admissions rather than specific majors, that program-by-program intensity does not change the broader comparison.

In practical terms, someone looking at both schools as whole universities should expect USC to be the tougher admit. UIUC remains a serious reach for certain applicants and especially for certain colleges within the university, but overall it is not typically considered as difficult to enter as USC.
