It's been a matter of great controversy for many years now as per here:

I suppose all you can do is try it and see if it's any better?
It would also depend on your stacking algorithm.
Your results are very impressive without all that mucking around.

If I get a large enough stack because they are dithered and each
Image does not have a lot of noise the stack is very clean.
But if my stack is not as large definitely darks work well.
I am finding flats to be a bit tricky and with virtually no cignetting not a lot of gain. Flat darks are hard if you do sky flats at dusk as the exposure length is constantly changing.
Darks are easy enough to apply. CMOS and bias don’t seem to get in too well.
