[1.14.3] Best practice for adding new ores

Hi All,

I am wondering what the best practices is for adding new ores to the game.  Should the custom ore extend Block or OreBlock?

As I work on my own mining item, I notice that different modders follow different methods (e.g. some Block, some OreBlock).

Is there a preferred way to either include or exclude all custom ore blocks that are added by different mods?

Thank you for the guidance.

Regards.
