calibre's conversion does many things kepubify does not. Off the top of my head:

1) It does proper sentence detection based on language rules using the ICU library with support for the actual language metadata used in the HTML
2) It includes the kobo.js file by default
3) It has a more extensive test suite
4) It can both add and remove kepub markup
5) Various minor things you would need to read the code to find

And finally since calibre will be used by many more people for many more books, over time the code will become much more robust
