Simple question: Which field type is more *performant*, Matrix or Neo?

I have to build a 60+ multi-site with different languages and I need to think about this architecture before building the *pageParts*.

Does anyone know which one of these fields uses fewer resources on the database?

Thank you

LE: I have found this:

*Performance
Out of the box, a Craft Matrix re-saves every block within that Matrix. If you have dozens of fields then this can take a lot of resources, meaning it takes a while to save. Ben (author of Neo) has built-in a superb feature in which the Neo field detects what is new and only saves the newly created content within the fields. Clever stuff!*

Is it true?
