I don't think this as a problem of trusting A over B. Those blogs try to
explain the attacks in detail, while the NIST standard is just a set of
recommendations that does not (try to) provide technical details of comparable
depth.
Although I prefer understanding things in detail, I think it's o.k. to say in
documentation that "we use ... cipher because it complies to ... standard".
