Yes, very good review. I'd love an R5, but the price kills any chance of purchase in the foreseeable future.
I don't agree that the R6 image quality is similar to that of the R. Comparing the downloaded R6 and R RAW files from DPReview's studio shots, converting to dng and importing into Lightroom, I found the R files to be noticeably sharper at all but the highest ISO values.
