Which one is the difference between Product and ProductRepository?

Question

In Magento 2, which one is the difference between Magento\Catalog\Model\Product and Magento\Catalog\Model\ProductRepository?

Using both of them, seems they have the same methods, so I don't know when I should use one or the other.

Answer 1

I am not 100% deep knowledge of this.

But i am pretty sure that you should use

\Magento\Catalog\Api\ProductRepositoryInterface

As it can use for both api and model layer

See the magento document:
