For wide angle lenses the optional screen with split-image focusing aid is better, although I hardly use my EOS with R wide angle lenses, since there are a number of R wide angle lenses that won't fit because of the protruding rear element (R 19, R24 and R 35/1.4). For my EOS RT body, because of the pellicle mirror, I had Bill Maxwell work on the standard screen which is now brighter and more contrasty. It is worth noting that EOS screens (and probably focusing screens of most, if not all, AF SLRs) are optimised for brightness rather than contrast, and thus are not as good for manual focusing compared to, say, that of the SL and R8.
