It's been a while since I was in University, so I'd probably answer this question more directly with a web search to see opinions and ratings, such as https://www.niche.com/colleges/search/best-colleges-for-computer-science/ (as one of many examples).
Personally, I went to UCLA for Computer Science in the mid 90's, and it was a pretty solid program. UCLA is listed as #19 on the list above from 2019 (but it looks like every school on that list would be great regarding studying CS).
One thing to consider in regards to choosing a university is also the exposure to other curriculum, cultures, and opportunities. Yes, you are choosing the best school, but "best" really gets defined about you and what YOU need. I think it is important to be happy to sustain the level of dedicated work that University demands. And to surround yourself with opportunities that may show various ways to get involved in a variety of fields, or areas in between different fields of study.
For example, UCLA is in the sprawling metropolis of Los Angeles, which is glorious in the amount of things you can find there. You are not in the heart of silicon valley or anything, but you are surrounded by movie studios, with many employees of Pixar and Dreamworks and other computer centric companies in various fields around finance and movies.
