There is no answer to the question ‘which is better?' Similar features and even some shared strengths make it hard to pick a clear winner. Carefully consider your purpose and your ability to help choose what system is best for you. You will be well on your way to creating the content you want
Wordpress is a blogging app with ambitions. It's clean, simple and it's easy to customize its code. As a CMS, in addition to regular blog posts you can use pages, but pages are not assigned categories or sections, making configurable menus a bit of a challenge. Embedding apps is also a challenge, and often we need to resort to using iFrames. It's much easier for your clients to get their heads around the Wordpress back-end.
Joomla is a portal framework - supporting communities, embedding apps and having configurable layouts menus, with articles assigned to sections and categories. It's much better as a CMS than Wordpress, but its back-end is often just too confusing for non-developers. Joomla's codebase follows a more modern MVC (Model View Controller) implementation.
Joomla's codebase and database are larger than Wordpress's.
There is an abundance of Wordpress Themes, and a relative paucity of Joomla Templates.
Both have their delights and frustrations. Often I've gone with Wordpress, only to find down the line that my client wants an extra feature that would have made Joomla a better choice. And sometimes I've I've gone with Joomla, only to find that my client doesn't have the technical aptitude to deal with its complexities. 5 years ago Wrdpress and Joomla were quite different animals, now they are becoming alike in many ways.
Why don't you install both, and explore for yourself.
Wordpress and Joomla are both CMS for specific purposes. It's like saying apples and oranges which is better. We know they are both fruits, right? So also, Wordpress platform is suitable for the articles/blogs centric project whiles Joomla is for more extended online work like a complete site with many resources apart from blog-like pages. Thank you.
Both have some advantages as well as disadvantages Like wordpress is simple to use,excellent for blogging or sharing thoughts in a sequential manner,even the most elderly of users can get the hang of it quickly.But if we consider disadvantage of it, it is not developer-friendly.on the other hand joomla is friendly for all types of users - Designers, Developers and Administrators.
Each has its own advantages and disadvantages. In my opinion, Joomla is the best, if you want to save your time. Word Press is easy to use for beginners, however it lacks of friendly towards web designers and developers.
