In the question“What are the best TVs?” VIZIO M-Series 50" (M50-E1) is ranked 1st while Sony X850E 75" (XBR75X850E) is ranked 48th. The most important reason people chose VIZIO M-Series 50" (M50-E1) is:
The M-Series is the best pick for HDR content in this price bracket. Compared to its direct competitors, it offers the best HDR experience because it has all the essentials for true HDR playback that its competitors lack: local dimming, fairly high peak brightness level, and a wide color gamut. Its deep 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 a slight increase in overall picture quality - the black levels become deeper by a small margin, so highlights will stand out further. Colors look vibrant in both dark and bright scenes, and the panel can reproduce the wide range of colors required for true HDR playback. In addition, it can also get bright enough to light up these colors sufficiently for HDR details to stand out, thanks to the peak brightness level of ~400 nits.

Pro Great for HDR content
The M-Series is the best pick for HDR content in this price bracket. Compared to its direct competitors, it offers the best HDR experience because it has all the essentials for true HDR playback that its competitors lack: local dimming, fairly high peak brightness level, and a wide color gamut.

Pro Supports both HDR10 and Dolby Vision
The M-Series can play all HDR content because it supports both HDR10 & Dolby Vision formats.
Pro Great picture quality
The M-Series looks great with vivid colors.
Dark scenes look amazing with great details, thanks to the panel’s contrast ratio of roughly 5500:1, which means it’s capable of producing blacks that are 5500 times darker than the brightest white pixel the screen can produce. This can be pushed slightly further to about 5800 with local dimming, which results in a slight increase in overall picture quality.
The colors are quite lifelike and accurate even without any calibration. They will look vibrant even in bright scenes because of the panel's high peak brightness levels of ~300 nits for SDR & ~400 nits for HDR.
Even in a decently-lit environment, the picture quality of the M-Series won't deteriorate by much. The panel is good at handling reflections and it can get adequately bright to fight off glare.
Pro Decent at handling glare
The M-Series is decent in bright environments.
The colors won't look dull thanks to the panel's high peak brightness levels and good handling of reflections. It's bright enough to fight off glare with peak brightness levels of ~300 nits for SDR & ~400 nits for HDR, and the intensity of reflections are reduced by panel's semi-gloss finish.
Pro Comes with Chromecast built-in
You can stream content to the M-Series from smart devices or apps that support streaming media to Chromecast.
Pro Has a remote app for iOS & Android
The M-Series runs on VIZIO's SmartCast OS which has a brilliant, well-integrated phone and tablet app for iOS & Android. It can turn your smart device into a fully-functional remote, which makes it easy and convenient for you to control the TV without the physical remote. It's also particularly handy for text input, especially when it comes to searching for content from streaming services.
Pro Interface is ads-free
The M-Series has no ads on its interface.
Pro Decent for HDR content
The X850E has a wide color gamut that allows it to reproduce the colors necessary for true HDR, and it has an average peak brightness level of ~400 nits that allows it to light up these colors properly. Thanks to that, HDR pictures look decent and highlights will look fairly good.
However, the HDR performance can’t get better than that, due to the average peak brightness of ~400 nits which isn’t really enough for details to truly stand out, and it lacks local dimming.
Pro Good for sports
The X850E looks fluid thanks to its excellent color uniformity and decent handling of motion.
It can display large, same-color objects like football fields really well - they will look natural and uniform.
Fast-moving objects, like football, will also look smooth. The panel only requires ~14ms to fully change the pixels color, resulting in fast-moving objects not leaving any trails on the screen, eliminating virtually all motion blur.
Pro Great ecosystem of third-party apps
The X850E 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 Decent picture quality
The X850E looks really good in dark scenes, thanks to its decent contrast ratio of 4500:1 and excellent black uniformity.
It can produce blacks that are 4500 times darker than the brightest white, and the black uniformity is especially good - there’s barely visible flashlighting, where edges of the screen have a light on them when displaying a black image, and the screen is evenly bright. This makes it perform really well in dark scenes.
Colors look vibrant because of the panel’s high peak brightness levels of ~350 nits for SDR & ~400 nits for HDR. With these brightness levels, it can get bright enough to fight glare. Along with its great handling of reflections, pictures will still look good in decently-lit environments without dull colors.
Pro Interface is ads-free
There are no ads on the X850E’s interface.
Pro Excellent motion interpolation capabilities
The X850E can increase the framerate of content to either 60Hz or 120Hz.
It guesses which frames are missing based on the previous and next frame, and inserts the missing frame in between them. This produces a really strong soap opera effect, where images look really smooth.
This might look weird to some people that don't like it, but the X850E can do this really well for those who enjoy it.
Pro Suitable for gaming
The X850 has a relatively low input lag of ~35ms that makes it a decent pick for gaming. Most players will feel in sync, however, it might be a little unresponsive for competitive or demanding gamers.
It’s also acceptable for HDR gaming because the input lag does not increase in HDR mode.
Pro Excellent for 24p content
The X850E is an excellent option for those who watch content from an antenna/satellite box, DVD/Blu-ray player or Apple TV. It can detect eliminate jerky playback that is common in content from these sources.
Pro Offers best value for screen size in this price bracket
The X850E has the largest screen size at 65” for the cheapest when compared to its direct competitors. Similarly-sized models from its direct competitors cost much more.
Con Local dimming could be better
Unless you're in a really dark room and the brightness is set to really high, the effects of local dimming on the M-Series isn't very noticeable. You'll be able to see some differences in dark scenes, but it's not enough to improve the picture quality by much. The contrast ratio with local dimming enabled increases from roughly 5500:1 to 5800:1, a difference that has little impact on the overall experience.
Con Interface can be sluggish and slow
The interface of VIZIO's SmartCast OS can sometimes be sluggish. Some users have reported experiencing choppy animations, frame drops when browsing through the menu, and slow response to input/selection.
Con Mediocre sound quality
The M-Series sounds too bassy and some details will be drowned out because of that. There is also noticeable distortion at high volumes.
Con Not suitable for group watching
The M-Series has a narrow viewing angle that makes it unsuitable for group watching.
Its picture quality gets worse when viewed from off-center angles. At just ≥20° off from the center, the colors start looking dull and blacks turns into grey.
Con Lacks TV tuner
The M-Series, along with several of VIZIO's latest TV lineups, does not have a TV tuner built-in. If you plan to watch local over-the-air broadcasts, you will need to purchase a TV tuner separately.
Con Not the best value choice for gaming
The M-Series is not the best choice for gaming in this price bracket due to its relatively high input lag of ~40ms. Gaming TVs requires low input lag so the player won't feel out of sync, which is why most of the TVs suitable for gaming have a low input lag of ≤20ms.
This may be negligible to some, but input lag can make a world of difference to demanding or competitive gamers.
Con Not suitable for group watching
The X850E has a narrow viewing angle that makes it unsuitable for watching with groups.
Its picture quality starts to deteriorate significantly when viewing from just ≥20° away from the screen's center. The colors will start degrading really quickly.
Con Might require color calibration
Some viewers might find the X850E’s white balance to be slightly off out of the box, so a brief calibration might be required if you notice it. Fortunately, all the optimal color settings are available on the internet and isn’t hard to find.
