I wouldn't have said anything until you dragged me into the conversation

it would appear DPAF has a low-light advantage and AF speed advantage all things equal.

The jury is still out on this one until people start testing the actual cameras. The spec looks promising, but there are a lot of details missing from the EV-5 rating. For example, in extremely low light, does the M6 II drop back to contrast detect AF? The camera would still be doing AF, and would technically meet the spec, just not in the way that everyone is assuming. It is also likely that the AF cycle slows dramatically at these light levels. The M6 II could actually be less sensitive than the M50, but maybe the M6 II lets the AF cycle run for twice as long to collect more light.

Years ago I tested my 5D II with the 100mm f/2.0 against my M2 with 22mm f/2.0. The 5D II is rated at EV -0.5 whereas the M2 is rated at EV 1. Even though the 5D II had the much better spec, the M2 completely blew it away in low light AF. This testing was with a high contrast static target. The 5D II would keep hunting, but never lock. The M2 cycled at the usual pedestrian speed and locked the first try every time.

I forgot one one other data point.  Your EOS R is rated EV-6 @ f/1.2 whereas the Nikon Z6 is rated EV-6 @ f/2.0.

Likewise, pixel stripped sensors will ultimately have a sensor metric advantage. Depends what you want. Likewise, Canon will always make better glass. Sigma is the wild card here though on both sides...

Every camera manufacturer produces very high quality lenses. The notion that every single Canon lens is better than the equivalent lenses from all other manufacturers has no basis in reality.
