I've seen both of these in Currys/PC World and both looked very good. However, there are no stores in my area which can demo TVs from an off-air signal, so the performance with SD and HD sources is unknown.
I was particularly impressed with the off-axis performance of the Samsung, as there was hardly any drop off in colour or brightness even at very wide viewing angles.
