RC vs RC231 for Mavic 3 and Mavic 3 Pro?

[lomposlapos]

I have the DJI RC Pro, RC, and RC231 controllers to fly Mavic 3 and Mavic 3 Pro.

My default primary controller is the RC Pro.

Which controller would you recommend as a secondary, (safety backup), the RC or the RC231? What are the differences between these two controllers when flying the M3 and M3P?
