It seems strange to be admonished, and at the end told you are right. I would argue with some on your list but not your general premise.
I was at a BBC event once where there was a band. The BBC sound person had to use the supplied mics, a box full of dynamic mics, a mixture of SM57s and Behringer’s 8500s. The SM58s stayed in the box and he used the Behringers. when asked why he said you cannot easily EQ out the response of the 58, whereas the Behringer has flatter response that is easier to EQ. It should be said that SM58 is a 60-70 year old design. The fact that I think my Sontronics Solo is far superior is nothing to do with the fact that the Sontronics factory is just round the corner from me. Before you ask, I bought it retail after trying several mics.
Still as someone from Shure once told me, the SM58 paid for his pension.
