Pros
Pro Setting up is very easy
Setting up a new Express project is very easy. It consists of installing a handful of libraries through NPM run a single npm install
and everything is ready to go.
Pro Great routing API
Express' extremely powerful routing API allows developers to do tasks ranging from building a REST API to building the routes for a simple web app and then take it to the next level by using route parameters and query strings.
Pro Great for beginner Node.js programmers
With a little learning curve, it is a good choice for new NodeJS developers to get started quickly. Express boasts great, thorough documentation.
Pro Express.js is in the Node.js Foundation Incubator Program
Node.js Foundation
Announcement here
The Node.js Foundation is a Collaborative Project at The Linux Foundation. Linux Foundation Collaborative Projects are independently funded software projects that harness the power of collaborative development to fuel innovation across industries and ecosystems.
Pro Relatively mature
Being a somewhat old Node.js web app framework and being one of the most widely used frameworks, Express.js has matured quite a lot during all that time. It's more stable than its competitors and a huge community backing it.
Pro Support for a lot of plugins
Express takes advantage of Node's NPM to distribute and install countless plugins made by third parties which solve almost anything a developer would want to do with Express.
Pro Has the largest userbase
It's by far the most popular framework for node.
Pro Great supportive community
Express has a big community with a lot of guides and tutorials written about it by developers that have been using it for quite some time.
Pro Good Oauth/Facebook integration with connect module
You can easily add oAuth integration/social logins to your next web app without much hassle, using this authentication middleware for connect.
Pro Has detailed information
Very simple and fast.
Pro Lightweight
Pro Massive ecosystem of middleware
If you have not already checked out the Express.js ecosystem of middleware, you should.
Pro Open Source
Symfony is open source and released under the MIT license.
Pro Easy debugging with a built-in debug toolbar
Symfony comes with a built-in toolbar that helps developers debug their applications during the development phase.
The toolbar is also extendable and new components, called panels can be added if needed to help with the debugging process.
Pro Great plugin ecosystem
One of the greatest strengths of Symfony is it's amazing and large plugin ecosystem, which comes as a result of it's large and dedicated community. Having a large number of plugins means less development time and more productivity.

Pro Highly active community
Symfony has one of the most active communities out of all the PHP frameworks. This is shown by the high number of commits made every day in the GitHub repo.
Pro Teaches you good practices
Symfony makes you be a better programmer. You have to deal with the latest object-oriented design patterns such as service-oriented architecture, dependency injection, interface abstraction, and so on.
Pro Uses YAML/XML/PHP/Annotation
Symfony makes use of XML, YAML or PHP annotations to create configurations in order to tell Doctrine on how properties of a certain class should be.
Pro Powerful event system
Symfony has a powerful built-in event system that allows you to add flexibility to applications and makes it easier to maintain the codebase down the road.
Pro Great templating engine
Uses Twig, which is a simple and easy to learn templating language that can also be used as a standalone engine, outside the framework.
Pro Uses Doctrine ORM
Symfony makes use of the Doctrine ORM to add an abstraction layer over the database in order to maintain flexibility without having unnecessary code duplication.
Cons
Con No single recommended way of doing something
Express considers itself to be a "minimalistic unopinionated framework", it basically lets the developer determine how their project will be organized. On one hand, this gives anyone terrific power and flexibility to use any library they want for a certain task and to organize their project structure however they want. But on the other hand, there's no single recommended way of organizing things, which can be a trap for beginners and experienced developers alike and result in unmaintainable projects.
Con Settings
Too many configurations.
Con Very hard to install
Setting it up on webhost without a console is difficult.
Con Promotes bad development practices
Such as annotations via comments.
Con Doctrine ORM
Symfony Standard Edition, which is the most widely used distribution, comes integrated with Doctrine, the most resource hogging ORM library.
Con You need a lot of files to display a single page
For a simple hello world page you need about 5 files.
