Here we find a substantial difference due to the objective for which the CMS was designed.
Prestashop, as I have extensively argued in this article, was created for sale and therefore, regardless of the graphic theme you choose, when you open the site it immediately jumps to the eye that you are browsing in an electronic store. All the elements that make evident to the user that he/she is on an e-commerce website are clearly visible and immediately recognizable.
On WooCommerce many of these features are not available. To overcome this problem you will need to integrate additional plug-ins in the site to implement it, for example:
- plug-in for multi-language site
- plug-in for the multi store
- product comparator
and others.
The use of these plug-ins, among other things, weigh down the site and this may cause a problem of page loading speed and the consequent abandonment of the site. All this would negatively affect the ranking of the site from the SEO point of view (search engine ranking).
From a graphic point of view, although it is true that WooCommerce has several compatible graphic themes, it is also a reality that the final graphic design of these sites looks much more like a company website than an electronic store. Why? Simply because WordPress was not conceived to do e-commerce.
