What are the benefits of this platform? I'm thinking about working with it, but I'm not sure if it's the best one.

Well, I can tell you that Drupal is a pretty good platform, so you can work with that, and I think you won't be disappointed with the final product. But I'd recommend you to contact a company that'll help you decide on eCommerce solutions and find the best one for your website because it's not necessarily Drupal.
