Early on Canon had a clear price and quality edge. That's why there is so many devoted Canon users. Today the quality is even maybe slight edge to Nikon with D4s and D750, but price still leans towards Canon. Again in my market Nikon is king but only because the two pro shops push that brand. It all has to do with money
Canon had the AF perfected first back in the late film SLR days. That helped them a lot with Nikon competition.
