MLRaw is RICH. I'm still shooting MLRaw for sure, but GH5 is another tool in my bag. For most gigs I shoot with the GH5 4K60p and 1080 120fps as it's a better tool, if I'm shooting something that needs the richest look I use MLRaw. It's like the Mayweather Vs McGreggor fight, the GH5 is a MMA fighter, it's never going to beat 14Bit raw in a fight of colour accuracy and richness... however, shooting with an ML hacked camera you can't even shoot 4K 60p or 120fps... there's no comparison to be made in that regard.
In summary I'm still pretty impressed by GH5s colours and DR, especially coming from GH4, I don't think anyone could be dissapointed with this camera unless they use AF a lot, something which I basically never use since I shoot mostly vintage glass and anamorphics. (I use GH5 with Metabones XL).
