What are you wanting to do?
I use the AEV procal and pretty simple to use for my needs. Set tire size, gear ratio, center steering wheel, set tpms, set driving lights and a few other options. No experience with anything else.
If you have a Rubicon - I believe the AEV pro cal is the only unit that will allow you to turn your sway bar dash light off if you switch to a manual system from the e-disco system.
I've got the ProCal as well, very happy with it. Can't go wrong with the price. I already have a code reader so that eliminated the option of a superchips for me.
