These are the two sets i have been looking at for the last two months. I am getting the Sony. The biggest reason is that there seems to be just a lot less problems with this set. Although the Sammy with the led engine sounds great, (no light to replace), several of the owners have had the light engine replaced due to a loud humming noise. I have been reading both owners threads in this forum and the Samsung owners have had a lot of issues to deal with. Too many i thought were returning the set for replacements or calling a tech out. The Sony set has few problems and plus it got a great review recently on cnet regarding color representation and PQ. When i saw both sets in person i liked the Sony picture, it made me feel like i was looking through a window or i was in the movie. Overall i think the Sony is just better made and i think will last longer with less problems. If both sets had absolutley no problems i may lean to the sammy, no lights to replace, no maintenance upkeep equals more money stays in my pocket, but we dont live in that world. Just my 2 cents on this.
