How to choose best UX Bootcamps

Well, for the past few days, I have been researching the best UX design bootcamps, and I found many results on SERP. You guys can also see there are a number of websites that list many bootcamps in their articles. My concern is: what are the factors I should consider to determine which one is best for me? According to some articles, rating does not matter to find the best one.
Can anyone give their suggestions on this?
Thanks
