In general, I've seen no evidence camera brand/size/cost/complexity/etc drives the strength and power released of photographs produced.
Indeed, I like to ask photographers I meet on the street the question: "So, what do you shoot?"
If the answer is something like: "I shoot a Canon 5D Mark IV, with a 70-200 f/4 zoom and an 85mm f/1.4 prime," that tells me something.
If instead, the answer is, for example, something like, "I make photographs illustrating how gentrification in large cities leads to the displacement of low income families," that tells me something else. That would be a photographer I'd want to have a beer and conversation with, looking at her photos.
