Pros

Chromecast costs only $35 which makes the overhead to jump into the ecosystem pretty minimal on the consumer's part.
Pro Can be powered using TVs USB port
If you have a USB port on your TV, you can use that to power the Chromecast. The Chromecast is powered through a standard micro USB port.
Pro Does the processing on a different device
Unlike other set top boxes, the Chromecast just takes in a video stream in VP8 or H.264 format, and can stream that content either directly from the provider, or through a device that processes video to those formats. Because everything is done on a different device, you wont need to upgrade the Chromecast as often as other set top boxes, and anyone can play content from their phones, tablets, or computers.
Pro Available SDK means any app can utilize chromecast
With the amount of apps available on the Play Store, seeing that an SDK is available for any of them to use means that a large swath of apps can and do use Chromecast making for a very large ecosystem for what is a pretty cheap streaming device.
Pro Easily support multiple bands of Wi-Fi
Dual-band Wi-Fi support with 2.4GHz and 5GHz allows for easy connection to multiple different routers, this way no one is left out with a non compatible device as well as support for faster speeds which is helpful with HD content.

Cons
Con Limited OS support
The device is designed for Windows, OSX, Android and iOS. Linux support is limited and Windows Phone support is nonexistant.
Con Somewhat lengthy setup process
To set up Chromecast, attach it to your TV, download the Chromecast app on your host device, pair it, connect the Chromecast to your Wi-Fi, wait for the updates to download and from there you are ready to cast.
Con Needs registration
You need a PLEX account even if you use it on your local LAN.
Con Proprietary software
Unfree software.
Con No gapless audio-playback
Plex still does not support gapless playback of audio files such as mp3 or FLAC.
Con Playback error: This server is not powerful enough to convert video
More hardware requirements on Plex due to a useless/non-intuitive transcoder. When using lower spec hardware (eg SBC) Plex will not transcode or play HD+ videos. When compared to other packages (eg Jellyfin which transcodes nicely using FFMeg), Plex falls short on video playback and transcode settings to get videos to play (fastest/lightest option still fails).
