Ask HN: How do web dev bootcamps differ on prestige?

This question is directed towards folks who hire software engineers.

A friend is applying to bootcamps. (Literally asking for a friend!) I'm trying to help my friend out, so I'm trying to get a sense of what the difference in prestige between different bootcamps is.

If you were hiring for a junior web developer position and you were reviewing a recent grad from either A) The Flatiron School or B) Lambda School, which would you prefer? How strong of a preference?

(And is there any C) other bootcamp which would produce a strong preference?)
