I have the following:
Samsung 65" - UN65JS8500
Samsung 55" - UN55JS9000
Samsung 55" - QN55Q8FN
LG 65" - OLED65B8PUA
The Samsung televisions are solid but they cannot compete with the LG OLED televisions. In all fairness, Samsung is getting better with the QLED line but they still have substantial ground to cover. Black uniformity and local dimming are not where they need to be. It is very noticeable on the Samsung televisions.
FYI, I find
RTings to be a legit source for information.
