I have been collecting for a long time. I have little confidence in minion graders who likely know much less about the cards I collect than I do, and I have seen many bad or misidentified cards in slabs. Plus there now seems to be a growing industry in faked or forged slabs that may exceed the Christmas rack pack production for all I know
I get why if you are a seller, or a buyer and seller you need to deal with graded cards in today's market. It is just a necessary evil I am glad not to have to deal with in my own collecting.
But, if you enjoy what you collect and how you collect, it matters little what I or anyone else thinks
