Since the cart went ahead of the horse here a bit...
It all depends on the model and line you are interested in. As with most Mfgr's, the better spec'd sets are usually much more molah. I currently have 8 HD sets in my house, 2 are Sammy's, 3 Sony's, 2 Sharps. The latest is a UN65ES8000 (8000 series) and the picture is just incredible (to me) as I am a fan of true blacks and pure but not overpowering colors. Sharpness is right up there with the best of them as well. My 55" Sammy is still good but not quite all what the 65" is being the 55 has now been out well over a year now. Yes, time is technology.
My main living room set is a Mitsubishi Laser 75" which has wow factor. Granted the Sammy 65 is smaller but boy does it stop company in their tracks to look at it (plus it drops out of the ceiling so that maybe some of the wow factor on this set too i guess. (gotta be fair). Oh man, the pic is superb and even the audio quality is pretty good (not that you will probably wanna use it). The hand "waive" remote function is kinda weird and I won't comment on that here (yes, it's "almost" bs-crap but somebody probably does actually like it
cough, cough. Picture makes up for it, forgotten see ya.
The new Sammy 75 is a 9000 series (only model to date I know of in the 9K series) and that for a big set kicks royal hiney as well. I don't own this set (yet) but have played with it extensively at BB. The price tag may shy most away but I don't think Sammy made this set for the frugal folks... lol!
So high(er) end, late model LED Samsungs... ya got my vote!
