I have run RC on the following cars:

F90 M5
F93 M8
F92 M8
G80X M3
G80C M3

Now this is not a judgement on a product Ive not tried aka JB4 but to tell you why I did what I did.

RC is perfect for me and my shit 91 gas where I will NOT be running alternative fuels and mods. Its a plug, play, and walk away product that can install and remove rather easily (again JB can do similar stuff) but I just like how the product has been for my needs which is a slight bump in hp and speeds from digs to rolls.

If was into advanced fuels and high end mods like DP's and other items; JB would be my choice. But Im not. I just like the value for the gains I get along with the simplicity and the bluetooth app for convenience.
