The EH is not a true LED. It is a combo of both LCD and LED so it isn`t a True lit LED edge which is what the ES is. So if you look at the two side by side you will notice the ES to be about 47% thinner.
With that said the Picture and Features should be about the same.. the EH is just made with cheaper tech....

The difference between the TV's is like comparing a Big Douche VS a Turd Sandwich...
From what I know I would say don't get either of those tvs. You can get a better LED or a really good Plasma for the same price.
Try Sharp, Panasonic or LG
