I would personally go with natives since you can get and set values across plugins. With FindConVar you would have to rely on the server having the plugin/module with that convar. And since it's modular, that means having that plugin/module would be optional. At least with natives, you don't have to add checks to see if the plugin/module is even there or not. Just my view on it.

Edit: If you're just collecting data, forwards can work too.
