Sorry for replying so late! Here are some key differences:

• It’s very minimal, running macchina only shows elements and nothing else. All other elements such as bars, shorthand values, padding, spacing, themes etc. can be adjusted on the fly using command line arguments (so you don’t have to settle with any defaults and it doesn’t use a config file)
• If dependencies matter to you: Macchina has fewer dependencies.
• It supports themes out of the box (there’s 3 currently)
• It auto-spaces all your elements (this is something I haven’t seen any fetcher do)
• It offers a bar display for memory and battery usage.
• It has some elements that are not present in FreshFetch (but FreshFetch also has elements that Macchina currently hasn’t implemented yet)
• FreshFetch supports icons, but Macchina used to support icons. They were removed because the implementation wasn’t satisfying my needs, I might bring them back if someone would like to see them.

FreshFetch from the screenshots that I’ve checked out, looks very close to Neofetch, and that’s not really the point with my program. What I’m trying to do with Macchina is to set it apart while keeping it familiar.
