Bootcamps, and their associated certs, are good to fool your way past HR people who don't know better.
As soon as these folks get in front of me, they stand out like a sore thumb.
That having been said, if my boss came to me and said, "WBill, you need to be certified. I need a piece of paper that says you know what you say you know".... I'd likely use a bootcamp.
Remember the days people took pride in writing elegant code? When a big app was 7 megs.
