Pros

Pro Open source
Open Qoob is completely free and open source. It's hosted on GitHub.

Pro Has auto loading classes
This framework uses PHP's spl_autoload
methods to automatically load classes. This means that if the class is inside the project folder structure, there's no need to call, include or require it.

Pro Simple and lightweight
Qoob is made to create simple REST APIs and not full-blown applications. Therefore it's quite lightweight.
Pro Highly customizable templates
Joomla allows for heavily customizable templates to be changed from the admin interface without needing to hack.
Pro Powerful and user-friendly admin interface
Admin interface is constantly being iterated on to remove unnecessary legacy features and to streamline the interface. Resulting in a very clean and easy to understand interface that also offers a wide range of options.
Pro More than 8000 extensions
Which can be found here.
Pro Easy to pick up
Pro Great for social networking and commerce sites

Cons
Con Still under active development
This framework is still in beta stage and under active development. This means that a lot of stuff may be subject to change and some features may not be 100% complete yet.
Con Insecure
It's common-place for a Joomla-based website to be defaced, often very quickly. This is most often due to the low quality of extensions.
Con Extensions are scarce, badly maintained & rarely good
If it's not part of the default Joomla installation, quality extensions are rare. Joomla has a extensions library, but it is full of abandoned, dated or bloated components, modules and plugins.
