Con
Not good for Cross Browser Tests
Since it only tests via Chromium, it won't help you test inconsistencies between browsers like Edge or Safari. There are projects to get around this, but they aren't mature.

Pro
Runs a real browser
Unlike the other options here, this is a real browser, just without the GUI parts. This means the quality of the test is much higher, and lets you do things like save to PDF or images.

Codeless automated testing

Doesn't support a wide array of browsers and/or operating systems

Con
Free plan has limited time storage for test suites
If you are using the free plan, keep in mind that the test suites created there are scheduled to be deleted after around 2 weeks. Endtest will send you a notification email the day before mentioning "Test suites from users who are not on the PRO Plan get automatically deleted after some time," and offering for you to upgrade to PRO.

Premium version is relatively cheaper than most in the market
Their pricing plan ($79/month or $650/year) includes team plan upgrade, which means the whole team, regardless of the number of users, will only need to subscribe to the $79/month or $650/year plan. This includes unlimited test runs, test exports, recordings, etc.

It's mostly free to use
The free plan covers a lot, you can have up to 3 test suites, and you can run your automated tests as many times as you want. The pro plan includes some very advanced options that you might need only if you're working with a team (for example, the collaboration feature, schedule test run, API for Jenkins, etc.).

Top
Con
Heavy setup
You'll often end up having PhantomJS binaries connected via WebDriver to your testing framework, possibly using client/server especially if you want your test running with something else than Java. This means an overhead in terms of maintenance and performance, but still usually lighter than running a full browser (like Chrome, Firefox, IE).

Including bootstrap, grunt, ember.js, and YUI.

Con
Browser closes unexpectedly
It often happens when running on more then 5 (my measurement) JVM instances that the browser gets stuck and quits unexpectedly. This can be partially solved by running the instances one by one instead of parallel (this is a problem when testing Jenkins and Bamboo agents) but I don't believe this qualifies as a solution. The error is called UnreachableBrowserException.
See More
Top
Pro
Supports many browser standards
PhantomJS has full DOM and CSS parsing, JSON, canvas, and SVG support.
See More
Top
Con
Elements are sometimes not visible
This is an error which occurs with almost no reason, PhantomJS sometimes decides that it cannot click the element even though the element is intractable or enabled. This happens if you have to scroll to see the element (and these are not pages that load elements with JavaScript) which is strange because PhantomJS should catch the whole page if it is not loaded explicitly with JavaScript. This problem partially goes away with re-sizing the browser, but that does not really qualify as a solution. The error it raises is: ElementNotVisibleException.

Allows screenshots (either the full page or parts of it) if performing UI testing
There are times where you don't want to open up a browser for screencaps, that is where CasperJS comes to use, it can render the page using its own rendering engine and take and save a screenshot for you, all via the commandline

Top
Con
Cannot guarantee 100% accurate Webkit-based browser screenshots
QtWebKit is the rendering engine used by CasperJS. Keep in mind this is NOT the same rendering engine as Chrome; hence, if you want to be 100% sure of the results, you must run a Webkit browser (such as Chrome) yourself.

Written in JavaScript

Can run javascript code inside pages being tested
Can execute arbitrary javascript or load external JS into the page being tested. This feature is possible due to the presence of a rendering engine, and helps you see the effects of any client side scripting during your tests.

Claims to be "Insanely Fast"
It's a lot faster than fully fletched browsers and a lot lighter. Partly because it really only focuses on headless loading of pages along with their JavaScript (not taking really care of rendering or more visual resources).

Con
Fails to load many sites
As its JavaScript and DOM engine are mostly "just good enough" and because by design it'll report all errors and stop there, many complex sites will not load properly through Zombie.js.

Includes its own testing framework / assertions library
Unlike WebdriverIO, which lets you use various test frameworks and assertion libraries (e.g. Jasmine, Cucumber, Mocha + Chai), Nightwatch comes with its own BDD-style interface for performing assertions, based on Chai.

Con
Setting up in Windows can be a little tricky
Sometimes when setting up BrowserSync in Windows some errors will pop up. Most of the time this is because npm throws errors when trying to compile BrowserSync and some of the dependencies need Visual C++ runtime libraries. This is easily solvable by installing Visual Studio. Once it's installed, there should not be any more problems.

Works with any testing framework or assertion library
WebdriverIO lets you use your favorite testing framework (Jasmine, Mocha, Cucumber) and assertion library (Chai for Mocha). Other projects implement their own testing and assertion APIs, for example Nightwatch, Intern. It should be mentioned though that v4.2.16 has an incompatibility with at least tap v7.1.2: stdout/stderr written during a run gets lost.

Chimp.js, is an emerging web application test framework that implements easy sync tests using WebdriverIO, CucumberJS and Chai.

Tests run in the order they're added to the suite
In cases where you want (I know your test cases must be atomic) where you really really want your test cases to run in a specific order, maybe if the current one rely on those of previous case, you can use Qunit by setting QUnit.config.reorder = false and your test cases will run in the order you've provided.

Testing of Async operations can be a little tough at times.
Qunit, expects us to call the start() function before the Async function itself, and stop() after it stops. This can be a problem when you have no way of knowing, when your function will start or stop (your testing a number of dependent functions)
See More

Works really well if performing DOM Testing
All frontend developers already know the ease that jQuery framework has brought to their lives, in handling DOM events and accessing elements. Since Qunit was built as a part of jquery (is even used by jQuery itself for unit testing) hence it makes testing of DOM elements a lot easier.
