I agree with Willie!
I think the most popular and user-friendly CMS is WordPress. So many people use it because it has plenty of plugins, they are easy to implement. Recently I even used payment gateway fondy.eu/uk/cms/wordpress/ and I find it very handy.
I guess all CMS platforms have pros and cons, that's why it is hard to make the choice. If you are in search, my advice is to look through the review here https://www.webbuildersguide.com/best-website-builder/ecommerce/cms/ This source will provide you with the detailed info of the most popular CMS tools, so it will be easier to compare them.
