8x6 models have really bad black crush and posterisation in dark scenes, especially when watching streaming content. The 936 is far too expensive for the tv you get, nearly £1k of the price is for the soundbar/stand.If you're really into gaming, go with an 8x6 model as that (I believe) now has true 4K 120hz/vrr support. The 936 does not have true 4K 120hz (vertical resolution is halved at 120hz) with or without vrr.
If you want an all in one solution (ie panel and soundbar) and don't mind 4k gaming at 60hz, 936.
I own the 936, but will readily admit that value for money wise, the 8x6 models have it licked.
I'd go for (in my personal order but all three are better in different ways) LG, Sony or Panasonic.
