UCD vs UC Berkeley Chemical Engineering

DD accepted to Chem E at UCD and Chem E at UCB. Looking for input on both programs. She has visited UCD twice and plans to attend an overnight program at UCB soon. What are the pros and cons of each program? Is there a compelling reason to attend one campus vs the other beyond going by the campus “vibe” and how comfortable the student is at the campus? There appears to be more flexibility at Davis for changing majors should that be a possibility in the future.
