SLO has a much more developed and rounded business curriculum. You can choose from many more specialty areas like finance, entrepreneurship, international business, information systems, etc.
UCI's website "Students are required to complete 10 business courses that provide a foundation in essential core business competencies, followed by a minimum of 10 business electives selected from specializations. Students select a minimum of one of three specializations in Accounting, General Management, or Marketing. "
Looks like UCI only offers Acct, GM, and MKT specializations.
