Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Mature
Django CMS is a very mature project, with many core developers working on it constantly and adding new features and bug fixes.
Pro Can integrate with existing apps
Django CMS is more of a Django plugin which can easily be integrated with any Django app to add CMS functionality to it.
Pro Double click to edit
You can double click items to edit them or add pages directly on the website (as long as you're logged in as admin). It simplifies content creation and touch-ups.
Pro Easy to extend
Documents are organized in a tree. You can either create new content area type, new tree nodes, integrate complete existing Django app in the tree, etc. It's pretty easy usually.
Pro Internationalization (multi-language) support
Having a website in more than one language can be very challenging and DJango-CMS supports it well. Switching between languages while keeping on the page for example.
Pro Out-of-the-box Admin UI
Keystone comes with an auto-generated Admin UI, which makes things very easy for any task that can be completed using Keystone. In any way Keystone is used, the Admin interfaces saves a lot of time and makes any job easier.
Pro Keystone comes with Express already configured
Express comes out of the box already configured from Keystone or it can be treated like any other Express Middleware.
Pro Keystone has easy form processing
Using the data models defined by the developer, Keystone can validate forms automatically without any more setup. Form validation doesn't get easier than this.
Pro Many cool features
Great CMS with auto-generated admin, schemas...
Pro Easy to install and use
KeystoneJS is very easy to install and use.
Pro Easy email management features
With Keystone it is easy to set up an email management system for an application. It has template-based emails and it's also integrated with Mandrill (Mailchimp's transaction email sending service)
Pro Keystone uses MongoDB through Mongoose
Keystone allows the usage of MongoDB since it comes with Mongoose, the most popular ODM for node and Mongo, this means that anything that is built using Mongo can be built with Keystone.
Pro Numerous amounts of templating engines are supported
Keystone supports almost all templating engines out there. Although it uses Jade directly after a fresh install and it points to using it further, other template engines can be installed and used instead.
Pro Effective session management
Keystone has advanced and effective session management and authentication features. Logging in and signing up is easy and it even has password encryption out of the box.
Cons
Con May be an overkill for a simple blog
Django CMS project is a large and complex project, comparable to Wordpress. As such, it may be too much for a simple personal blog considering that it has many features that may never be used in that particular occasion.
Con It does not have a built-in roles system
Although registering a new user is very easy, there is not any roles system out-of-the-box. There is only a check box "Access keystone" which gives a user full administrative power. Adding different kind of users is only possible by editing the user data model.
Con Horrible documentation; Keystone5 is unfinished and the team dumped it for a whole (stripped down) new version
Team even admits to a lot of areas being undocumented. Just spent 5 months implementing Keystone5 just to have it marked for deprecation. Next version removes DB Adapters (the entire reason for us implementing it). This project is poorly managed, and extremely difficult to extend due to incomplete documentation.
Con No auto-reload and no good support for RDBMS
Does not have auto-reload in its backend.
Hard to debug.
Features found in document, absent in code.
No enough support to PostgresQL, no automatic migration

Con No default option to add pages in admin panel
Con It's hard for front-end developers with no MVC experience setting up views
Keystone follows MVC practices in managing routes, views and templates. Back-end developers with experience in working with MVC frameworks will find themselves at ease since the beginning, but developers who work on the front-end only will have a hard time finding what they are supposed to do to set up templates and such.
Con Some working knowledge of JavaScript, NPM and Databases is needed
MongoDB is required to be up and running and a Yeoman generator is used to generate the application. Although the prompt based start-up in the command line helps you a lot, it still can be hard for someone inexperienced with NPM and Yeoman.
Con Packaging externals libraries is tricky
Unless you want to import every JS.
