I have not seen a Samsung frame so cannot comment. Personally; I won't buy anything Samsung. The last product I used of theirs was the PS51E550D1R Plasma and some model of a 3D Blu Ray player that came bundled with the TV. This TV was superb.
I have spent time with a Panasonic HZ1000 (oled. Not sold in India). Its last years model. Aside from the lack of the latest Home Screen custom rom (The brand is slow in rolling out software updates), the display is first rate. The JX/JZ (led/oled) are current generation and more up to date. I'd buy a Panasonic any day over a Samsung. Throw in a LG oled and the decision gets hard. Honestly; you cannot go wrong with either.
