Between the Samsung and the Sharp Unit. I actually think the Sharp unit is sharper than the Samsung LED.

However, the Sharp unit suffers from one critical problem. Some movies will suffer from periodic frame stuttering. It's very brief but very annoying. This problem becomes awfully noticible the moment you turn of motionflow. Motion blurring is not a significant issue for this TV.

The odd thing is I've never been able to figure out why this stuttering happens, and it only happens to certain movies and dvds. Initially I suspected the problem to be due to the AC Ryan media player that was plugged in. Maybe it doesn't have enough processing power and then this problem pops up when I play some DVDs as well on my xbox360. Games do not suffer this problem. When I pop in Inglorious Basterds Blu-ray, there is no such problem as well. Chinese movies such as fearless, dragon tiger gate also do not suffer this problem. So I'm scratching my head right now. Is the stuttering/juddering because file encoding or the way it was filmed or because the unit does not have a powerful enough motionflow engine?

No idea, maybe I'll buy another Blu-ray (Star-Trek) to test it out. If that works flawlessly, then the problem must be isolated to either the upscaling or the processing power of the media player.
