It depends on your individual needs and the requirements of your project. There is no single 'best' e-commerce platform, as different platforms offer their own advantages and disadvantages.
To determine which e-commerce platform is right for you, it is important to assess your specific needs. Understand what you want to sell, how much you want to sell, and how you want to display the products. You may want to consider other factors such as scalability, cost of hosting, available plugins/integrations, and customer support.
If you are just starting a small online store, an easy-to-use platform like Shopify, BigCommerce, or WooCommerce could be the right choice for you. These platforms offer a range of themes, plugins, and other helpful features. They are highly popular, and provide the foundation for a lot of successful online stores.
However, if your store is more complex or you need advanced features such as marketplace integration, custom shipping rates, or real-time fraud analysis, you may want to look at platform like Magento, Oracle Commerce, or Salesforce Commerce Cloud. These more advanced platforms are more suitable for larger stores and enterprises.
Ultimately, it's a good idea to do some research and even experiment with some of the available platforms. There are many comparison guides available (like this one: https://www.slotkinpaint.com/blog/ecommerce-platform-comparison-guide/) to help you make a decision that best fits your needs.
