rotors & pads - any differences

I know about the ongoing challenge with Jeep warped rotors and pads....
luckily have not had that problem since the last change out.

Just curious about ongoing brake maint.
Have you found any differences in materials & install
at the dealer compared to the chains like Midas, Merlin, RX, Firestone,
etc
or - is it merely the caliber of the tech and how they were doing that day
?
