Anyone can tell which platform is best for creating an online eCommerce store?

Actually, want to make my own ecommerce store for promotional products. I am confused about whether to create a Website in Shopify or Magento ?

or which company is the best for this service?

I’d personally go with Shopify since they are super easy to integrate with anything else and setup is as easy as it could get IMO

100 percent shopify. Its SUPER easy to use, has everything you will ever need. Just remember - Use Quality pictures, dont play too much with the colors.

Pro tip, go to exchange marketplace and look at what stores are being sold, examine them, try to recreate them.
