The biggest difference, IMO, is the background. There really isn't that much out of focus with the OM; no softness or feeling of depth. Wide open on the OM looks like f/4 on many of my M9 shots. Again, thanks for taking the time to put this together. I don't often get into these discussions, but your images affirm my opinion that the smaller the sensor, the less control one has with the image with aperture changes.
