I honestly don't care about the exact refresh rate numbers too much. Latency is the more important thing anyway.

I agree refresh rate is often talked about, I reckon assuming short viewfinder lag. While assumption that fast data pipeline is also there is not unreasonable, it is surely not given. A short delay of image in VF - or latency - is indeed more important.

On the other hand, fast sensor (and VF?) refresh (can) be directly linked to AF performance. Other topic.
