I had the Sharp 70le857u in house for 10 days. I now have the 65f8000. No contest. The extreme bright room performance is similar. The weakness of each as I see it? The Sharp just can't get bright enough while keeping an accurate picture even though the screen itself is better than the Samsung's glossy screen. The Samsung, while having a less ideal panel, can get so darn bright with keeping an accurate picture. This is the first lcd I've liked as much as my Panny plasma, but this is better for this room. Oh, and $3k is a con for both.
