1. ISF calibration does not always produce the "best" results. The above post is correct in that a set can be tweaked to "ISF School" perfection, which an individual isnt going to hit exactly. One of the threads on avsforum discusses this in detail, and offers "The steaming rat method" with comments about that vs ISF calibration with someone who has gone in both directions. Sometimes tuned perfection just isnt as appealing as adjusting the set to get a looking through the window real life skin texture type orientation, guided by steps, set up disks etc. Individual mileage may vary, so to speak. The concept that everyone agrees on what looks best obviously isnt true.
2. I have never seen a plasma with motion artifact and there are no differences in the scalers or glass used in commercial vs consumer plasmas with the exception of the coating I mentioned due to FCC classification. Motion artifact has been an inherent problem with Flat Panel LCD displays and is most obvious in sporting events to me. BUT- LCDs have gotten better on this.
