What is the easiest UC to get into?

I'm curious to know, what university or college in the United States would you consider the easiest to gain admission into? Are there any specific factors that make certain institutions more accessible for prospective students? Is it solely based on academic performance, or do other elements such as extracurricular activities, letters of recommendation, or even financial status play a role? Additionally, could you elaborate on the potential implications of choosing a university primarily based on ease of admission, especially in terms of academic rigor and future career prospects?
