Which one does Google prefer, Microdata or JSON-LD?

Question

Here Google says they prefer JSON-LD:

JSON-LD is the recommended format. Google is in the process of adding JSON-LD support for all markup-powered features. The table below lists the exceptions to this. We recommend using JSON-LD where possible.

But in other article, in the What is microdata and JSON-LD markup? section, they say they prefer microdata for content:

Microdata and JSON-LD are two different ways to mark up your data using the schema.org vocabulary. It's best to choose either microdata or JSON-LD and avoid using both types on a single page or email. Google prefers microdata for web content.

So what's up?

Solution 1

The document that recommends JSON-LD is more recent and it clearly states that Google recommends using JSON-LD where possible (over Microdata) specifically for the following reasons:

• "The markup does not have to be interleaved with the user-visible text, which makes nested data items easier to express, such as the Country of a PostalAddress of a MusicVenue of an Event."

• "Google can read JSON-LD data when it is dynamically injected into the page's contents, such as by JavaScript code or embedded widgets in your content management system."

Solution 2

The Google Developers article is more recent. Then, I would choose that information as the prefered one.
