I'm the person who insists that the cropped 1080p on the EOS-R is of good quality. It appears based on my reading of the specs that the RP is missing this ability. The RP only has a crop mode in 4K or in 720p (HD), which means that it is probably cropping the Full HD read out for the 720p crop rather than processing the 4K data. It also doesn't have C-Log or the 10-bit output. The crop on the RP is less than on the EOS-R, but otherwise it doesn't look like it is offering much to consider.
