Looks like a good test Fred.. I must say I prefer the HaRGB shot.. Detail is what I look for in an image, the HaRGB oozes detail, and despite missing some of the outer nebulosity and the dim stars, its still my favourite of the two... (as a matter of fact, I much prefer less stars or heavily reduced stars produced by NB filters..)
I had to have a double take when I read DSLR next to your name in a deep sky imaging thread!
