I tell you my experience with the UN65JS8500 did not go well. I owned it for several months, got a screen replacement, and my dealer was kind enough to even attempt to swap out for an all new UN65JS8500 which ended up looking exactly the same. Samsung insisted, despite my protests, that the TV looked the way it was supposed to (see my photos below of the Blu-rays of Amazing-Spider-Man 2, Spy, and Freddy vs Jason all of which showed excessive edge light issues/bleeding/clouding). That galled me, and I knew they had to be wrong. But it was actually I that was wrong, the replacement TV looked identical so I guess it did look like how it was supposed to. But I would never own an LG IPS panel TV, so if it was between those two I guess the Samsung. I will tell you having purchased a Sony XBR65X930C to replace the Samsung, that the Sony dimming function, and contrast is so superior to the Samsung that IMO Samsung engineers should all be canned. That's not even mentioning how much better the motion on the Sony is. The 3D can be a little soft on the Sony however and does appear a bit better on the Sammy. But YMMV. If I had to choose between those two however, I'd have just kept my small 42 inch Panasonic Plasma with the defective sound. Lol.
Did you settle on a TV set? I just noticed the KS8000 is currently only $300 more then then JS8500 and that might be a reasonable alternative. It would have full UltraHD Premium certification with 1000 nits.
But no 3d. Gotta have 3d.
Both sets have their perks, but for my needs the Samsung won by default. The 3d viewing on the LG required sitting at least 13 feet from the set in order for the images to converge properly.
I hope your luck is better then mine, though if your motivation is 3D, then the 3D on the UN65JS8500 is stellar. I think if I had to choose between the LG IPS and the JS8500 I would have picked the Samsung as well. Just make sure you put the JS8500 through it's paces. As I stated above, I used several blu-rays and found that the edge lighting glowing disengaged me from the enjoyment of what I was watching so much that I just had to give up and get the Sony which, while still an edge lit LED, absolutely controls the edge lit glow so much better for whatever reason. Is it the dimming algorithms Sony uses that's superior? Perhaps the dispersion materials Sony uses is superior? I don't know enough about this technology yet to be able to use always the correct terminology possibly, I just know what my eyes tell me. Work it hard to make sure you're okay with it until your return window runs out.
My return period expires today, which is why I went to HH Gregg yesterday and put all the LG's through their paces watching native 3d clips and 2d to 3d samples. The 55 inch OLED 3d looked amazing at 9 feet viewing distances, but 65 inch sets (which is what I was interested in) required at least 13 feet.
For the most part I agree with you (except that I have "0" light bleed issues). I chose the Samsung because of the viewing distance required by the LG's passive 3d.
Well, I'd have to say " Great Picture " is a major factor !!
Consider yourself lucky you aren't having to deal with Android TV. Despite the fact that I love the picture on my Sony, the Android TV interface has a LONG way to go. And the problem is, since it's the operating system it causes issues with everything. Tizen is snappy and smooth comparatively. Sure, with Android TV the sky is the limit as far as apps. It's a great idea, but it is buggy at times. There are things I love about it, but nothing with it is ever quite as easy as it was with the Samsung. But picture quality is paramount.
I've always preferred Active 3D myself, and IMO it is excellent on the Samsung.
I feel the LG has more 3d Pop when compared to the Samsung. I had them side by side for a week before moving the Samsung to the bedroom. The whole not being able to do DV is what is killing Samsung since all the 4k hdr streaming content is supporting DV more and more
