Like any sibling rivalry, WordPress and Drupal have been competing to be the best content management system (CMS) ever since their ‘births' in 2001 (Drupal) and 2003 (WordPress). While both considered to be very good website creation tools, they have different strengths. While WordPress may be more popular with over 140 million downloads, Drupal is more multi-faceted, as it is recognized for being “one size fits all”. Despite their varying strengths and weakness – in terms of available themes and plugins, update frequency, and skills required – what makes one option better depends on how their differences fit with your business's needs. When it comes to sibling rivalry, every person has his or her favorite. So how do you choose your favorite CMS? Consider and prioritize each of your website's potential needs or requirements, and read on to see which ‘sibling', WordPress or Drupal, is best for you.
Need: Ease of Use
WordPress is extremely easy for nearly anyone to learn to use. Equipped with a basic understanding of HTML and CSS, you can take advantage of its impressive plugin library (hundreds of thousands of plugins), to add a variety of features to your content management system (CMS). This, combined with the many theme options, allows you to better customize the tool to your website's needs and build a high-quality website in no time. In addition, as you can see from this screenshot, WordPress's easy-to-understand user interface clearly lays out and marks each of its functions and customization options. 
This makes it faster and easier to learn – especially compared to other software platforms such as Drupal – allowing you to dedicate less time to building the website, or less money to having someone else do it. This means more time and money you can spend developing other important aspects of your business.
Need: SEO Strength
Really, you can't go wrong with either option when it comes to building a site for SEO purposes. WordPress and Drupal were both designed to produce the most search-engine friendly sites. However, with SEO tactics evolving and becoming more content-focused, Drupal may be the better choice in order to get your site to the top of the search engine results page (SERP). See the next point to learn why.
Need: Large Content Capacities
It's no secret that producing helpful and unique content is extremely beneficial to a brand's search engine optimization (SEO). Search engines recognize this as being a very reliable indicator of the quality of a site for its users. It's simple – the better the content on your website, the more likely it is that your site will appear at the top of the SERP. Businesses that value this SEO strategy should use Drupal because this software is able to “handle hundreds of thousands of pages of content with ease.” Therefore, for websites that also offer a lot of content due to their industry or purpose, such as e-commerce sites (e.g. Amazon.com) or sites that offer an article directory (e.g. eHow.com), Drupal again is the easy choice.
Need: Enterprise Accommodation
Due to the reason above, Drupal is also the better option for enterprises. Drupal's system includes strong version controls and access control list (ACL) capabilities, which make it very secure for big businesses and their immense amounts of content. WordPress, on the other hand, is typically only recommended for small to medium-sized websites because its default backend was built with the intention of being used for blogs. This means that heavily posting content on a regular basis can cause slowness and general difficulty when using WordPress. Another advantage of Drupal for enterprises is that it maintains maximum stability of your website through automatically scaling to accommodate various numbers of users.
Need: Multiple Author Participation
For businesses with this need as a priority, WordPress is easily your best bet. From its beginning, a main focus of the WordPress system was to be able to accommodate several authors, making it ideal for serious publication sites and sites that use guest-bloggers. However, there are several features of Drupal which helps to increase website privacy, which brings me to my next point…
Need: Maximum security
Unfortunately for WordPress, security issues come with being the category leading software with not just thousands, but millions, of installations. This means if you are concerned about hacking threats and are unwilling to install third-party plugins in order to secure your WordPress installation, Drupal is the better option. Drupal takes security very seriously and has covered its users for common security vulnerabilities, as well as provides them with security reports (like the one below) regarding their websites and installations of the software.
Therefore, banks and other businesses that house a lot of private financial or personal information should certainly use Drupal. You can find more information on Drupal's security features here. If you would still prefer to use WordPress, be aware that it lacks compatibility with older plugins. This means any new updates WordPress releases will not work with your current installment, given the use of these add-ons. Not receiving these updates will make the business even more vulnerable to hackers, break any current plugins, which then also means potentially breaking the site entirely. To avoid these risks, make sure to use newer plugins or update them in a timely manner when usingWordPress.
