In the question“What are the best TVs?” VIZIO M-Series 50" (M50-E1) is ranked 5th while VIZIO P-Series 55" (P55-E1) is ranked 19th. 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

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 Highly versatile
Suitable for gaming, movies, and sports, the VIZIO P-series is one of the most versatile TVs in its price range. While the combination of low input lag and fast response time makes the TV suitable for gaming;, the VIZIO P-series also does a great job of processing highly dynamic content, such as sports. Furthermore, the TV’s uniform blacks, excellent local dimming, and reasonably high peak brightness makes it an attractive option for home theater.
Pro Good for gaming
It has great motion blur handling abilities and a dedicated gaming HDMI port with a reduced input lag of 15.9 ms makes the VIZIO P-series quite suitable for gaming.
The TV’s excellent motion blur handling is directly related to its ability to change the color of each pixel 80% of the way in just 3.9 ms so you won't notice any trails on rapidly moving objects. The VIZIO P-series by far outperforms all the competitors on the market when it comes to this.
Pro Picture looks good from an angle
The 55-inch model of the VIZIO P-series has excellent viewing angles because of its IPS panel which preserves correct colors and shades no matter the angle between the viewer and the panel. This property makes the TV ideal for watching with a group.
Pro Can increase media's frame rate
This TV is an excellent choice for those who like to ‘speed up’ the regular 30FPS media, sourced from cable/satellite boxes or old DVDs as it can boost up low frame rate content up to a whopping 120 frames per second rate. Some people call it a ‘soap opera effect’, but technically the process is called interpolation. Additionally, it’s worth mentioning that this TV’s biggest competitor: the TCL P607 cannot interpolate motion.
Pro Compatible with HDR media
The VIZIO P-series is suitable for HDR-enhanced content because of its full HDR10 and Dolby Vision support. The HDR10 and Dolby Vision are currently the two flagship HDR formats used in the multimedia industry, which means that all the new HDR movies and shows are compliant with either one of those formats.
It’s also worth noting that in the HDR field, the VIZIO P-series outperforms its competitors, including the Samsung MU8000 which lacks Dolby Vision support.
Pro Good build quality
The VIZIO P-series feels solid and rugged because its frame and stand are built from high-quality metal. In comparison, the most significant competitors of the VIZIO P-series: Samsung MU8000 and TCL P607 have their frames and stands built from plastic.
Pro Has an excellent remote app
This TV comes with a brilliant, well-integrated phone and tablet application which can transform your smart gadget into a fully-functional remote. The application is particularly handy when you need to input some text, for example, while searching content on YouTube or Netflix.
Pro Compatible with current-gen consoles
This TV works fine with all the current generation consoles, including the Xbox One X, PS4 Pro, and Wii U, because of its 4K 60 Hz support.
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 Bad for HDR gaming
This TV is not a good choice for HDR gaming because its dedicated gaming HDMI port does not have enough bandwidth to support the HDR-enchanted input. This means that you will have to use a regular HDMI input port to feed the TV with the HDR content. The problem here is that the regular HDMI input has 43.5 ms input lag which is too high for fast-paced, competitive gaming.
Con The 55-inch model has low contrast
The 55-inch VIZIO P-series TV has significantly lower picture quality than the 65-inch and 75-inch models. The 65-inch and 75-inch models use a VA panel while the 55-inch model has an IPS panel. The main difference between those is that the VA panel has, on average, four times higher contrast ratio than the IPS panel; Thus, the VA panel can reproduce more vibrant and more in-depth scenes.
