Easy math isn't it ?

Remove the RGBW (LG ) then you are left with a Sony IPS & Samsung VA .
Which one to go will depend on your room condition and seat position .

Alright, will take the leap of faith and give this XF70 a try. Hopefully the black levels won't annoy me that much as I tend to watch some horror movies where it's mostly dark background lol. Will buy from Senheng @ 11street.my, cheapest so far for RM2250.

Then maybe next few years can kumpul money buy a better 4K TV haha (or maybe future is 8K liao?)

Nope , it is a RGB TV
The first thing you need to decide , is between VA or IPS.

The Panasonic and Sony are IPS while the rest are VA.

For brighter and bigger room , we normally recommend people to buy an IPS .
For dimmer and bedrooms , go for VA.
At this price point , they aren't going to make a day and night difference .

The Sharp model is an Android TV which has wider color gamut but without the better motion handling features.

Panasonic TVs always have amazing out of box color accuracy because that is the principle of their brands , which is great because people don't hire calibrator for their TVs of this price range.

The Samsung model has amazing contrast as usual but it is short of a few features (like smart remote control) this year.

Sony's TV has great picture processing features and I find XF7000 to be slightly brighter than last year X7000E , which is a good deal.
