We are able to test gurus, Prabhupada has passed these tests many times, please check out his many question and answer sessions on Youtube.
I have an opposite view in some respect to your own in that someone denigrates, insults and belittles smacks of genuineness, as the fakes will be trying to butter us all up to get our cash etc, so will pander to our whims.
I don't think Prabhupada claims to hold the knowledge but simply refers to the Vedic literature in most cases. He lived the life and followed the rules, he lived by example. Really I am unworthy to try and sell him to people, I should really find his exact words on the subject and post them, there is some confusion though spread by the fakes.
There is plenty of material on this.
