I think I have heard MORE people complain about their selectable lockers after installing them due to issues with either air lines or electrical issues than those who disliked their auto lockers. Now I am talking about full case auto lockers like a Detroit locker and not the lunch box lockers.
But it also depends on where you live and the type of weather you drive in. If you live where it snows a lot of people do not like auto lockers because of the way they can affect handling in snow & icy conditions. This would be the biggest reason to go with selectable lockers over auto lockers if you have winter road conditions.
