Wix-fetch vs wix-http-functions

I need to work with data from a SQL Server DB, exposed in a REST API. I don’t understand what are the differences if I use wix-fetch or wix-http-functions. It seems that with any of them I could do the same operations. Which is the best option?

Wix Fetch is used to access an external API (using get, post, etc). Wix http is meant to build your own api on top of your Wix application, which others could then use (using fetch).
