They are both Mid-range LCD TVs .
If you are not in rush , probably just wait the new 2019 models which are going to launch in roughly 2-3 months .

There will be quite a dramatic improvement on the upcoming Full Array Local Dimming system and wider viewing angles on VA panels .
Again , I expect the Mid range ~ High end ( at least RM 4k and above )  of LED LCD TVs from major brands to get an upswing in 2019 .  So if your budget fall within the range , you may want to hold your horse for a just a little longer.

Else the entry level 4k TVs are pretty much going to stay the same as last year , with even less features to save on manufacturing cost as the trend has been continuing for awhile.
