Specifically, going to a boot camp is both a time (3-4 months) and a $$$ (20k - 30k) commitment. They will teach you the tools of the trade well, e.g tools and frameworks and will make sure you come out with a certain level of knowledge that fill most junior level roles.
However, if you have a bs computer science degree, you probably won't get much value of of these boot camps other than learning the tools of the trade, which are things that you can pick up on your own since you have a solid cs foundation.
However, it's not a bad option if you have both the time and the money, and feel that the commitment of a boot camp will be beneficial to you.
bur the quality of these boot camp varies and I would only recommend going to the highly recommended one, eg hack reactor, hack brite, app academy, and recurse.
For you specifically, the only things that you'll get of a bootcamp are probably: 1) An expedited and structured learning process 2) Mentorship and peer support 3) Introduction to startups in the valley looking to hire entry level, junior developers
However, if you feel compelled and really want to attend a bootcamp in the valley, I have heard good things about: Hackreactor and Hackbright for web-development App Academy for mobile development Insight Data Science and ZipFian for data science
Hope that helps.
I do recommend to everyone getting an MSCS that they take the thesis option and do a project relevant to their desired job.
