>>4185668>Shutter speed does not affect noise.It affects exposure, exposure affects SNR. In tis case it's equal because the collected light works out to be the same (same intensity, one gets 4 times the area but 1/4 the time).
For long exposures it also introduces another source of noise, temperature.
Also because they didn't use equivalent apertures the GH6 may be more affected by diffraction. But yeah noise-wise they look about the same. Still not happy because it's not the apples-to-apples comparison I wanted to do.
