The larger 55" models seem to have an issue with flashlighting from the corners. My 40B6000 does not, but I think it has more to do with its size. The XBRs I really have not seen but have heard good things. Let your eyes decide, and really try to spend some time in front of these 120hz sets. The one I have, the B6000, was very hard to watch, it actually made me sea sick. My 60hz sets do not have this effect on me, nor does my Sammy 58B560 plasma.
