When you take a single video/painting/image from a creator without any background or understanding of that creator it loses most meaning, context is everything.
Now Peter does has a very good/close relationship with Canon and there is no doubt there is a touch of the sales team in there and he is, he would agree, a bit of a gearhead, but as a creator he has always been honest and open about his process, he has taken the time to explain not only his techniques but the thought process behind the decisions about those techniques. He is motivational (for some) and his comments on his motivation are very important for his brand, if he says he is feeling like he is going into auto pilot with his video making I believe him, he raises some interesting creative questions as well as gear questions. 'Struggling' artists tend to make better art, if you are forced to rethink your creative process it can make you a better creative, he is looking at the gear from a content creative point of view and how each feature, or missing feature, will interact with his creative process and for me that is a more interesting point of view than a straight review.
You can take it either way, model X doesn't have Y feature is a good thing (obviously it isn't), or because model X doesn't have feature Y I have to work on my creativity (but I'm going to keep my old camera that does have feature Y anyway for when I need it). Or even, Canon came out with something new, buy buy buy.
I like that he at least talks about his creativity and his process. About what he thinks of his creativity and his output.
Over caffeinated? Watch his videos, he is a coffee addict and aficionado!
