Just my 2 cents worth... having had the R5 and the G9 on a "shoot" with work last week, using both similar (the G9 being just the backup really, with the 2.8 35-100) and editing them back home.. while the G9 is flat out the best camera in terms of usability, ergonomics and enjoyment (and speed!) when you need to do a little more to the pictures, like pulling out the shadows, etc - the amount the R5 can cope with is incredible. This was a rooftop shoot per se, of model x product, and while the G9 is tack sharp and really dang good, trying to pull the RAW files doesn't yield many benefits in comparison to the R5. Given how much I just enjoy the G9, it really does make me think about the full-frame models they do. The Canon, while great just doesn't have the same incredible usability that Panasonic have really got!
