Should I Switch Platforms? Is Wordpress (In Serps) Worth The Trouble?

I have a big commerce site and I've heard that website's on wordpress platforms (custom) rank better. Does anyone have any knowledge on this? I would love to have it (ecommerce) on a wordpress because I have heard It is highly better functional and has tons more plugins I could utilize but before I jump the gun I wanted to ask. I am sure the next thing I will be ask is my site's url and it's Garden Delights Nursery . I would love some feedback on this.
