CMU vs UCSB vs UCI

I’m waitlisted at CMU for the Information Systems major. The deadline for the Priority List is coming up soon, so that’s why I’m making this thread now. I’m admitted to UCSB and UCI for computer science and computer science/engineering, respectively, with pretty good financial aid ~17k per yr, while CMU my estimated financial aid is basically 20k a year, leaving me about ~43k per year. Thus, would it be worth it to go to CMU over my other two choices and accrue a decent load of debt? Thanks for any replies.
