i would go LG LH90 over the edge lit B6000. The B6000 has visible lighting that plagues many of these sets in the corners and isnt nearly as good as local dimming.
However, id steer clear of the LH90 as of right now--there are really bad audio syncing issues with that line. of course not everyone has them, but many do. check out the forums at avs. apparently fixing it is a PITA since LG isnt aware of it (at least when i checked, which is recent). otherwise its a very nice tv. the box is fucking HUGE, like two times the size of other tv boxes...for some trivia lol.
