Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Cross-platform
Chrome and Chromium are available on almost every device nowadays
Pro Latest Blink
This is the browser Blink is made for and developed alongside.
Pro Sandboxing
Every tab and plugin runs in its own subprocess so they will never affect the whole browser ,however that consumes more memory than other browsers
Pro Completely Open Source
Both Chromium and and its rendering engine Blink are licensed under the BSD-license which includes no copyleft unlike the GNU or Mozilla Licenses.
Pro Access to Chrome's extensions
Chromium can access the Chrome Web Store and all the extensions hosted there can be installed and used on Chromium.

Pro Supports all of Google Chrome features
As Chrome is based on Chromium they overlap in supported features. Chromium syncs between devices, automatically updates, has great built-in developer tools, installs extensions without a restart, includes a combined text bar for entering URLs and searching and has excellent HTML5 compatibility just like Chrome.
Pro Bare
It does not have any extensions preinstalled and focuses to be a web browser.
Pro BSD license
You can do almost anything with the code.
Pro Gets constant updates
While the Chromium-based browser haev to adapt their code to the update before release, original Chromuim doesn't need it so it gets updated more constantly and frequently.
Pro Chromium sets the standard for Web Browsing
Since Google Chrome is the most used web browser, and that browser along with many others is based on Chromium, Chromium sets the standards for the internet and for security, and Firefox will always be years behind.
Pro Backed by Google
Chromium was first released as a large portion of Chrome's source code as an open source project by Google in september 2008. The idea was to encourage developers to review the underlying code and to contribute in making Chrome cross platform and port it to Mac and Linux as well.
Nowadays Chromium is a large project with a huge community that's standing behind it but still Google continues to take an extremely active role in Chromium development. This ensures the longevity and constant development and improvement of the browser.
Pro Does not come with Google
Unlike Chrome it does come wihout any Google account requirement.
Pro Tor sets the standard for safe and private browsing
If you follow their instructions religiously, Tor is the nec plus ultra in terms of safety and privacy. For the time being at least.
Pro Access hidden .onion sites
Pro Portable
Can be installed and run on a portable device such as a USB stick.
Pro Free and open source
Pro Uses the Tor network
Pro NoScript and HTTPS Everywhere installed by default
Pro Relatively fast
Pro The only browser package which includes a gateway built-in into TOR, a network where you can actually browse the web completely anonymously
Privacy. It's fundamental. And this browser has enabled and keeps enabling people to lookup things they don't want their ISP/ government or surveillance marketers to see.
And what's better they won't know a thing about what you searched.
What is visible to the outside world however is the fact: you make use of TOR and probably the TORBrowser this client / citizen of ours is using TOR to obfuscate his /her traffic (=~anonymize ).
Pro Safe
Tor is just as safe as Chrome or firefox, as long as you don't visit malicious websites.
Pro Based on Firefox
Firefox is a great browser, and tor is built on it
Pro Open source
Open source builds trust on using the program
Cons
Con Lacks privacy options
Con High RAM usage
Due the sandboxing, Chromium also eats a lot of RAM , which can be a problem for machines with smaller RAM.
Con No official builds
There are no official builds available so you have to rely on a third party distributor
Con Not possible to disable WebRTC
Con Fat, slow, and another piece of google spyware
Con Lacks support for certain common media formats
As Chromium avoids bundling any proprietary software, media that requires proprietary codecs or formats such as AAC, H.264, MP3 and Flash will not play by default on Chromium.
Con Can be dangerous / only available as Source
There are plenty of unofficial Chromium distributors and every one of them can disable specific features (like sandboxing) for their build, so you will never know what you get.
Con Under BSD License
Con Must adapt new browsing habits
It is not recommended to do several things TOR browser that users would want to do in a normal browser, such as visiting social networks and banking.
Con Not made as your daily browser
It does not support many modern features due security and is pretty slow.
Con Extremely slow
Caused by the tor network the browser depends on.
Con You will hang on every recaptcha
Con Not secure
Firefox isn't as secure as Chrome.
Con Tor is very outdated on Firefox code
It's not that it uses the same browser engine, just look at the logos.
Con Dependant on Mozilla
Since it uses gecko.
Con Did not install
Will also not delete either.
Con Does not guarantee perfect anonymity
Unlike what most users would suspect.
Con Using Tor on Android is still not great
Samsumg users will never use it.
Con Open Source
Anyone can hack the source code and insert malware.
Con Too many supporters
Tor has so many supporters such as brave, which makes it more popular. This is another thing how tor will be unsecure.
