The problem with this statement is that what system is really a good one?
I've had issues with three different manufacturers, one of the brakes was a flagship model and is still one of the best disc brakes ever made. Still leaked.
Like I said, if you have a home base where to do maintenance and repairs hydro's are a good choice, but at least for me there have been too many issues, most of which were home serviceable but could have potentially ended a tour.
