I played with other people's M240 files and I took several of my own that did little for me in terms of the rendering/color department. I also feel that way regarding the images I see out of the M246 when compared to the MM9 as well. Simply put I don't like the CMOSIS sensor and what it does but I digress for reasons that I don't want to beat a dead horse as I moved on from owning a Leica M for now.
As I say in many threads - there really aren't any bad cameras these days but some are simply a better fit for others. The M240 didn't fit into my camera bag where as I lived with a M9 since 2009 until 2014 when I decided to commit to Sony FE (although it has its own issues separate from Leica ones.) I don't think that most will argue that the M240 is not a more responsive camera than the M9 but many bought the M240 and went back to the M9 after not loving what it produced.
