This competition comparison, in this context, is not very relevant to SHOP. Rather, the relevance is competitors that offer the same qualitative services, expandability, hosting quality and the like.
How much analysis did you put into this? I know you tried Shopify personally and you are very happy with their service, but don’t think they are the only ones offering these services. I talked to a person who has been setting up online shops for a number of years and the way he talked about it gave me the impression that Shopify is just one of many options. Have you tried any other highly rated system like Magento or PlentyMarkets?
