The degree won't guarantee a job. I've talked to people at some of the bootcamps in SF, and the hiring rates and salaries are very good, something like 90% hiring rate at an average of $80-90k, which in general is a great entry-level salary. (And keep in mind that many of the 10% that don't get hired didn't seek jobs because they went off to try doing a startup).

I'd do the bootcamp, then do to school if and only if you feel like your lack of a CS degree is holding you back in your career. It may turn out that the degree is unnecessary: you can succeed and thrive in this industry without a degree, and never feel held back by your lack of a degree.
