Your JS9000 might've been a bad one. It shouldn't have any trailing in motion, and it shouldn't look washed out either. I had an EG910/9100, and while it obviously had great black levels, everything else wasn't up to par at all IMO. Haven't owned the EF9500, though.
I've had both the EF9500, and now have the JS9500. Motion is about the same on both.
Make no mistake, the OLED had a better picture. Duh. But once you get the JS9500 calibrated to your liking, it isn't as night/day as you'd think.
But man, I can't wait to get an OLED with low input lag.
