What are the benefits of having a SD card in a RC2 controller vs the drone mini 4 pro itself? Where is the best option for one? Or should I just put one in both?  My last drone was an origional Phantom.

What are the benefits?
None ... you don't need a card in the controller.

Hi there,

Thank You for reaching out. We are truly sorry for the inconvenience you are experiencing.

It is recommended to have a MicroSD Card in the drone and RC2. Here are the reasons why you need microSD card into DJI RC2:

1. It is for caching videos. Note: Videos cannot be cached if a microSD card is not mounted. Meanwhile, you can only preview low-definition files after tapping the Playback icon on the screen of DJI RC2 when the aircraft is powered on. If the aircraft is powered off, no files can be viewed through the remote controller, because the files are transmitted from the aircraft in real-time.
2. It is for screen capture and recording. The screenshot and screen recording functions are only available after installing a microSD card. When the microSD card is not installed, a prompt will appear stating “Install microSD card”.
3. When the microSD card is not inserted, it is unable to copy internal storage files to the microSD card Currently, the internal storage cannot be accessed by computers or mobile devices.

I hope this information has helped to clarify your inquiries. If you have any other questions, kindly let us know. Thank You!

You were asking what benefits?
What you were given is just a list of completely unnecessary things you can do with a card in the controller.
But there are no benefits.
