Shopify is the superior choice based on our scoring, but only just, getting 4.5/5 stars, while BigCommerce gets a 4/5 rating.
While both Shopify and BigCommerce offer excellent out of the box functionality, Shopify has a significant advantage when you compare its third-party apps and integration ecosystem.
You can find thousands of custom apps on the Shopify App Store (6k+ as compared to under 1k for BigCommerce), and most developers and freelancers are also quite knowledgeable about it, mostly due to the fact that Shopify is more popular.
Secondly, Shopify offers a comprehensive suite of retail features and native POS hardware. BigCommerce primarily focuses on e-commerce and does not offer its own native point-of-sale (POS) system like Shopify does.
