The H9 is no better in low light than any of the other similar cameras.

They are all prone to noise in low light due to using a small overcrowded sensor.

There is actually one SLR-Like camera that can be compared to a DSLR.
That is the Sony R1.
It uses the same sensor that is used in some of the Nikon DSLR cameras.
The only problem is the price.
The Sony R1 list price is $999.

For less than that, you can buy a DSLR camera.
