Technical support is the most valuable feature. Many eCommerce platforms do not have a good support infrastructure. BigCommerce does an amazing job of supporting its product.

BigCommerce also has a design capability for merchants to use widgets to change page layouts. This is very useful because merchants can make design edits and not need to contact their developers.

The user interface is very fast and they use a CDN for website delivery, which helps merchants sell more because the websites are fast-loading.
