From discussions I have read in the past, it seems to hinge on how often you open the safe. The electronic locks are a lot quicker to access; just punch a few numbers and open the door. The mechanical ones you have to turn so many turns right, then so many turns left, etc, etc. Some people get tired of it and just leave the door unlocked which defeats the whole purpose of having a safe. It would seem that a clever manufacturer would be able to offer an option to have both on one door setup so that if one failed, the other would still be able to open the door. I would spend a few extra bucks for that.
