But when possible, I think it is best to just nail the exposure. Which then means exposing on mid tones, not histogram.

I agree. But, if you have a low contrast scene, utilizing ETTR would place the mid tones, and the other tones in a range that would result in a higher signal to noise ratio...therefore lower overall noise in the image. Why would this not be better than exposing to place the midtones in the middle of the histogram?
I guess the underlying question that I have is: How do you define "nail the exposure"?
