Yes, DJ1 is def better smoothness wise IMO. But, I do get some artifacts then on the E6.so is judder worst with real cinema only ,vs dejudder on 1 ,i could use dejudder 1 as it seems a pinch smoother than real cinema .
I guess it is a matter of random artifacts vs judder all the time, if either matter to you.
There is a good case for either, no mode is perfect and you have to choose with your own eyes. Motion is different for everyone.
