In my humble opinion, although the argument can be made that the Nikon outperforms the Canon Mark IV in this area - how much better does the average photographer need? I do this for a living and this performance far exceeded my expectations and I can see the immediate impact that this ISO performance will have on my images - especially the ones shot at night and/or under poor lighting (high school football, basketball, wrestling, etc).
We'll see how it performs covering the Pirates game this evening.
