I guess I am going
Samsung or LG. Jut so many different models and don't know what i will gain by going for the new Samsung models over last years.......
Samsung @ 43" - They use a mix of panel types, recent buyers of their 43" TVs have found they come with IPS type which, like the Sony will perform badly in a dark room. Minus the better motion of the Sony.
LG @ 43" - They exclusively use IPS panels and will perform awful in a dark room.
Hisense at 43" - They exclusively use VA type panels which means its the only option at this size to get a good panel.
Philips at 43" - An outside option, not a sure bet at VA like Hisense, but a better chance at getting a VA panel than Samsung and LG.
Maybe now you can see why I recommend Hisense!
At 50" it would be different, since there are also some models from the others that match Hisense's performance.
I already took these things into consideration writing this guide here:
My best value TVs, 2018-2019 Edition which warns you regarding the Samsung/Philips.
One of the reasons I wrote the guide is because of the differences between models at different sizes. It takes away the stress of having to compare models pointlessly when we know that they will come with bad panels, or we know there is a chance they will.
There is also an argument to be made at smaller sizes just to buy the cheapest TV you can, just because none of the TVs at smaller sizes are really fantastic anymore. Manufacturers stopped making even mid-range models at this size some years ago.
