Don't worry I am not planning on OSC. Been there done that. They are great for brighter targets but struggle with dim objects and narrowband.

The Kodak True Sense LRGB colour filter array claims 2X increase in light sensitivity so perhaps 3X is true between mono and colour. I always thought it was less but the gain factor may be what I was confusing with QE. Like high ISO on a DSLR.

Most people would go with an OSC simply because it's a lot more convenient and simpler to run than having to contend with filter wheels, filters etc. Less to setup and still takes good piccies. A mono camera, filter wheel, filters etc etc, is a big investment. Great for a permanent setup, but I feel can be somewhat of an overkill if you want to just haul a light but good setup around, to use visually and also take piccies with. In any case, taking pics through filters reduces the sensitivity and resolution of your mono camera as well.
