Welcome from ND, I'm a new flyer with a mini 3 also. Don't be intimidated, these things are fun and easy to fly. I have learned a lot here and you will too.
I fly with both. I get much cleaner transmission with the RC Pro. Especially in areas of high interference. And I have a BVLOS waiver, and fly out 2 miles regularly. The RC2 will work, but I'm more confident in the RC Pro for better transmission...
