A question that is often heard, as if the use by famous brands decrees the validity of one software system over another. I can only be a bit polemical and sarcastic in answering this question. Let’s start by saying that there are updated rankings regarding the use of the most renowned CMSs, where WordPress has always reigned supreme and consequently in the ecommerce field WooCommerce. This data also says nothing about the quality of the CMS; otherwise, it would be easy to compare Windows to Linux and Microsoft Office to Libre Office, solely based on commercial success. Libre Office can be far superior, but if in schools and offices MS Office dominates, the cost of training staff is the first obstacle, meaning the Microsoft product is more widespread because few know how to use the products of its competitors.
The mechanism of success of these CMSs is the same, namely training and habitual use. This is precisely why WooCommerce is more widely used even among large brands. Large companies rely on communication agencies for the creation of their ecommerce, and these often use WordPress, simply because they know it better than other CMSs. Ironically, even the Shopify platform has achieved rapid success thanks to this mechanism, as communication agencies are heavily skewed towards the marketing side and consequently look for simple and ready-made alternative solutions.
