Take the XF, no question about it. I had both. I still have the 8.5mm XF (and since bought the 12mm also). There is no contest. It is one of the best EPs out there near that focal length. The XF is superior wrt every aspect of optical performance: contrast, transmission, off-axis correction for astigmatism and false colour. Not a marginal difference either. It's also a lot lighter and smaller. Works extremely well even at f/4 (Stratus is of little use at f/4).
