Pros
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.
Pro Doesn't require calibration
You will not need to spend extra time and effort calibrating this TV because of its great out-of-the-box color accuracy. The TV's average color error dE is only 2.34 which is far below the level that can be perceived by a human eye.
Pro Works well as a home theater TV
The 2018's VIZIO M-Series is an excellent option for those who are looking for the heart of their home theaters that would not break the bank because the TV offers decent dark scene performance and an excellent size for its money.
Cons
Con The remote looks outdated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.
Con CON Doesn't play HDR well
This TV has noticeably worst HDR performance than a lot of its direct competitors because of its limited color gamut and mediocre peak brightness.
Con Can't speed up low framerate content
Unlike many TVs of 2018, the VIZIO M-Series lacks the frame interpolation feature which means that you will not be able to boost up the framerate of content you're watching artificially. Interpolation is a significant feature for those who, for example, like to watch good-old Blu-ray as it can make it look noticeably smoother.
