In my testing the GH6 already does everything I would need in a still camera with great autofocus, stabilization, fantastic high-resolution mode, and a great selection of lenses. In addition, it is a full-featured hybrid video camera with slightly lower than leading performance auto-focus.
The dilemma I face is searching for a use case that would justify carrying the GH6 kit vs my cell-phone camera. I have Samsung Galaxy S22 Ultra with five lenses built-in ranging from ultra-wide angle to 100x zoom, and 12mp to 100mp native resolution. Although it doesn't go to ISO 100,000 it manages high-quality images in extreme low-light using multi-exposure and computational photography which also works well for HDR. For video, the stabilization is far better than GH6, especially when filming while walking. Video modes up to 8K are supported, including high-frame rate modes. The image quality for stills is good, and raw shooting is fully supported. The picture quality I get in both stills and video is excellent and can be further enhanced with post-processing. For general family and travel photography the cell phone is generally good enough. I thought the GH6 might be better for sports photography and brought it along for my grandson's football game shooting with the PL12-60mm in pixel-pixel mode at 4K60. I brought home a lot of video clips, and with some editing posted on Facebook. At the next football game a week later I had returned home so my son-in-law used his iPhone to capture video for that game. I compared the iPhone sports video to my GH6 video and preferred the iPhone video.
So far the only use case I have found where the GH5/6 is clearly superior to a modern cell phone is for telephoto photography while on safari using the PL100-400mm. I don't normally shoot birds, but that is another potential use case, and probably why the M43 forum is full of bird photos.
