I re-did my recent M31 with the trial version of PixInsight. I have to say I am convinced, and I'll be purchasing a license soon. The color balance was much better right from the start with PixInsight.
Taken from a Bortle 5 suburban back yard. Takahashi FSQ-106EDX4 at f/3.6 with the 0.73x CR Reducer. SBIG ST-8300M at 1x1 binning, with the FW5-8300 5 position filter wheel. IDAS LPS-D3 36mm unmounted filter for luminance and Astronomik Deep-Sky 36mm unmounted RGB filters. Losmady G11 Gemini 2, guided with a piggybacked AstroTech 65EDQ and an Orion StarShoot autoguider.
