I use a 10" f4.8 newt, capture times might be lower but noise is noise and in the end the sensor with the least noise wins.

Thanks Rick, that makes a lot more sense now. In my mind it was initially just a direct comparison between cameras, however, I now realise that it's not as straight forward as that

I could not find the numbers but the AA/UV/IR filters in each camera could have quite different transmission rates for the Ha wavelength. And this target is very Ha rich.
Thanks Luka, you're right - that could also be having an affect. Makes you wonder if the filters may differ between models or whether its just between manufacturers.
