My preference is good picture quality, though LG provides much more features in this budget, but i would like to know more about picture quality,sound and durability.
I haven't checked the LG LB6200 model but I've seen Sony W700B and I can say that it's very very good when it comes to PQ. Can't say about durability as they're pretty new and sound is not much expected from a flat (thin) panel LED TV. You demo both of these models with same content, your own content in a pen drive.
