Wordpress database $ wpdb and get_option ()

So, I develop plugins that create interaction and delete the database using get_option functions.

Now I have seen several tutorials showing how to use the global $ wpdb method to get values ​​from a database.

What is the difference between them and one is better than the other?

Using WordPress helper features (not limited to get_option()) ensures that your plug-in is cutting-edge if a new version of WordPress makes changes that could potentially affect your code.

But I develop plugins that manage user data and forms, and in such cases get_option()does not offer the versatility that I need without writing many composite arrays or without tracking several parameters. For multidimensional information or for cross-referencing, related data records for a plugin are $wpdbmuch better - you can structure your own tables and sort / organize as you like.
