In the question“What are the best TVs?” Sony X900E 49" (XBR49X900E) is ranked 6th while LG UJ6300 55" (55UJ6300) is ranked 170th. The most important reason people chose Sony X900E 49" (XBR49X900E) is:
The X900E looks true-to-life with really deep blacks, clear details, and captivating colors. Pictures look realistic with lots of details. There’s great depth to them and you’ll be able to see everything in the picture stand out. Dark scenes are excellent with nice shadow details that are not overly dark to the point where some details get drowned out. This is thanks to really deep black levels, enabled by the panel’s contrast ratio of about 5500:1 which means it can produce blacks that are 5500 times darker than the brightest white. This can be pushed even further to over 6500 with local dimming. The colors are lifelike and accurate even without any calibration by the user. They will look really vibrant even in bright scenes because of the panel’s high peak brightness levels of ~500 nits for SDR & ~550 nits for HDR. Even in a decently lit environment, the X900E’s picture quality can still hold up as the panel is great at handling reflections and it can get bright enough to fight off glare.

Pro Google Assistant is available
The X900E runs on Android TV that has Google Assistant. It has voice commands that are pretty useful as you can open apps with it, ask for the weather, and even turn the TV off.
Pro Excellent at upscaling low-res content
The X900E can upscale 480p, 720p, 1080p content to 4K with no issues. All the details are preserved and most won't notice any imperfections.
Pro Virtually no reflections
The X900E's panel has a semi-gloss finish that significantly reduces the intensity of glare.
Pro Great ecosystem of third-party apps
The X900E runs on Android TV that has access to the Google Play Store. The Play Store has a nice selection of apps, but normal Android apps won't work unless they support Android TV.
Pro Interface is ads-free
There are no ads on the X900E's interface.
Pro Excellent at handling highly dynamic content
The X900E can display fast-paced or rapidly-moving objects very well without any trails behind it. The panel only requires ~11ms to fully change the pixels color, which eliminates virtually all motion blur. It also has a native refresh rate of 120Hz that makes images look smoother.
Pro Great versatility
Apart from being an excellent TV for movies, the X900E is a decent choice for gaming and sports thanks to its decent input lag, low motion blur, great screen uniformity, and a 120 Hz native refresh rate that makes images look smoother.
The input lag of ~35ms is sufficient for most gamers, apart from competitive ones, to stay in sync with what's on the screen. The low motion blur of ~11ms and a refresh rate of 120 Hz ensures that everything will look smooth - fast-moving objects won't leave any trails on the screen.
It’s also viable for watching sports because the panel also has no issues with displaying large, same-color objects on screen, like football fields.
Pro Great at handling glare
Even in a decently lit room, the X900E's picture quality will remain more or less the same as in a dark room.
The colors will still look vibrant because the panel is bright enough to fight off glare. It has peak brightness levels of ~500 nits for SDR & ~550 nits for HDR, and reflections are also significantly reduced by the panel's semi-gloss finish.
Pro Excellent for HDR content
On top of the excellent picture quality, the X900E has everything essential to an immersive HDR experience: decent local dimming, great coverage of HDR colors, and high HDR peak brightness level.
Its excellent black levels are further improved with local dimming, which can make parts of the screen darker when the image calls for it. This results in an increase in overall picture quality with black levels becoming much deeper, so highlights will stand out further.
The panel can reproduce the wide range of colors required for true HDR playback because of its wide color gamut, which covers ~65% of the standard colors required for HDR according to the Rec. 2020 color space. This is considered great for reproducing HDR details, and it can display these colors accurately at different brightness levels.
Along with the the high peak brightness level of ~550 nits, HDR scenes will look stunning and you'll be able to see HDR details really pop.
Pro Good for gaming
The UJ6300 is a decent choice for gaming thanks to its extremely low input lag, excellent response time, and full 4K 60 FPS support.
In terms of input lag, this TV outperforms almost every currently available high-end TV. The low input lag makes the TV great for fast games. The motion blur is really low at ~17ms, so fast-moving objects won't leave any trails at all.
It’s also compatible with 60 Hz 4K input which makes it suitable for high-end console gaming.
Pro Has an excellent smart TV platform
The UJ6300 runs on the webOS smart platform. It has a great ecosystem of apps, ranging from media streaming services (Netflix, Amazon, YouTube, etc.) to third-party apps. Support for these apps are also first-class with up-to-date features and good performance; for instance, the YouTube app supports 360-degree video playback.
Pro Handles reflections well
The UJ6300 does a decent job at lowering the intensity of glare. Reflections are kept to a minimum thanks to the panel's semi-gloss finish. In fact, only around 1.9% of total light is reflected - a feat surpassed only by a handful of higher-end TVs.
Pro Fairly good upscaling capabilities
The UJ6300 can upscale 480p, 720p, and 1080p content quite well. The majority of details will be preserved, although there might be some artifacts on the sides of an image.
Pro Compatible with current-gen consoles
The UJ6300 will run content from the PS4 Pro and Xbox One X smoothly, and its input lag stays low at ~13ms even with HDR-enhanced 4K content. You will not notice any increased delay when switching from SDR gaming mode to HDR.
Pro Good at handling dynamic content
The UJ6300 is great at handling motion, making it a good choice for displaying fast and dynamic content. Fast-moving objects don't leave any discernible trails behind them, thanks to its low motion blur of only ~17ms.
Con Bad sound quality
The sound quality of X900E's built-in speakers is bad. It can't produce much bass and sounds rather flat. There is also noticeable distortion at high volumes.
Con Lacks support for Dolby Vision
The X900E currently only supports the HDR10 format for HDR content.
Con Not suitable for group watching
The X900E has a narrow viewing angle that makes it unsuitable for group watching.
Its picture quality gets worse when viewed from off-center angles. At ≥20° away from the center, the blacks start degrading into greys and colors will start looking dull. Brightness levels start decreasing at ≥50° away from the center.
Con The remote looks outdated
Apart from some tiny details, it seems like LG adapted their old remote from 2016 to the UJ6300. The remote is as basic as it can get. It does not have any smart functions that can be found on higher-tier LG TVs. In fact, it is very disappointing that this TV does not have LG’s new Magic Remote.
Con Suffers from minor image retention
The UJ6300 suffers from minor image retention issues. If a static image is on the screen for more than 10 minutes, it gets burned in and you'll be able to see it retained on the screen faintly, which is really unpleasant. Fortunately, this does not cause permanent pixel damage and disappears in around 5 minutes.
Con Can't handle intense glare
The UJ6300 can’t fight glare well in really bright environments because of the panel’s low peak brightness level. The brightness peaks at only ~170 nits for SDR, which is really low. Even cheaper and lower-tier TVs are usually brighter.
Con Dark scenes look bad
The UJ6300 fails to reproduce deep and uniform blacks. Its dark images look smoky and grey-ish, which makes many dark scenes look awful. Furthermore, the panel’s low contrast ratio of only 1314:1 makes the blacks look distorted and flat.
Con Some artifacts might occur
Because of the TV’s specific RGBW pixel structure, some unwanted artifacts might occur while the TV is displaying 4K content. The problem with the RGBW pixel structure is that only 75% of the total panel's pixels can produce colors, which results in lower quality and less detailed picture.
