My biggest issue with the LG in every review I have read on the Nanocell is that the image is quite poor in dark rooms or even dark scenes, the colour run is immediately noticeable and quite annoying. This could be a concern as I would definitely be watching TV or gaming in the dark etc.
The Samsung I am considering is the: QA65Q60T
Any recommendations on Sony 65inch?
Would ideally also like to buy the matching branded Soundbar, so in essence, my question would be which brand would have the best of both without paying a premium price?
Yes, I would agree with the above poster, unfortunately the Q80 is where the range really starts to get good and they're quite expensive.
The Q60s are expensive for what they are, they are more or less standard LED TVs, they're not very bright or with good tech to exploit HDR etc. I personally would not buy one, I think you'd get the same quality from a Hisense or less premium brand, so that would be my recommendation if you're tight on cash. It's up to you if you just want the brand and perceived reliability of course, but you're definitely paying for that and not necessarily viewing experience with the Q60.
For Sony the XH90 and XH9505 are their best LEDs. Very good TVs in every department, but expensive. I have the XH90 myself.
I would say if you have a certain budget worry about the TV first and save for the soundbar later. On the higher end TVs the sound is passable, it's not that tinny, it would certainly get you by. I'm not that well informed to recommend any soundbars though.
