I've done a few. I think the picture quality is about the same. This year's model is thinner by about half than previous models. The no gap mount is different. It's 2 clips on the TV, one on the left and one on the right, that hangs on 2 separate brackets that's attach to the wall. I've had trouble getting this model to sit flush to the wall. Not sure if it's just been that the walls are exactly flush or something on the bracket keeping from sitting flush all the way, but everyone I've done so far has had a 1/4-1/2 gap. I do control4 and there aren't drivers available for them yet but you can use a driver for a different model and it works just not with sddp.
