I do not have any of them, but from what I know, let Console 1 under own Sonar integration and use X-Touch with AZ Controller.
In that constellation, Console 1 will control own plug-ins and Mini will control the rest.
Several users have reported they are happy with Console 1 + MCU. Mini in most operations is far away from MCU (on physical level, that is not possible to change in the software), but (unlike with MCU) you can control any plug-ins (ProChannel, FXes, Synth, just do not forget to install and use "AZ ACT Fix").
I do not know what you mean with "scribble strips" on Mini.
PS. With AZ Controller + Mini it is possible to modify everything it does. Possible, but not easy for non programmers (AZ Controller presets are programs). In case you need some custom changes, just let me know (on my forum).
