Private vs UC for CS

Thank you all for your suggestions and helpful comments. Yes, we are from East bay CA and though I would have preferred he stay in CA and close to home, my son has chosen CS at NEU (Boston)
@PengsPhils as I mentioned above, NEU’s scholarship and loans ended up being only 7k above UCSC overall 4 yr cost.
Hopefully he chose the better school. Thanks again for all your very valuable inputs.
