I have both. And to be honest I like my mechanical better. The electronic is easy and faster to get in, but when it went down I could not get in my safe. Had to order a new lock and replace it before I could access my safe. The worst of it all, I ruined the lock myself. Had a friend that said if you had a strong magnet, you could slide it accross the front and you could throw the bolts and open it. Well, I got a super strong neodymium magnet. I gave it a try and slide it accross the front of the safe a few times and nope! It didn't throw the bolts which I was happy to discover. Then, I realized that I ruined the electronic lock by getting the magnet too close to the lock. It was two weeks before I received my new lock. Since then I have purchased another safe but with a mechanical lock. Have to say even though it takes a few seconds longer to get into, I like it better. The security of less vulnerability is what I like. I was told by a locksmith that when you elect for convenience, you sacrifice security. I know what everyone is thinking, I'm an idiot for trying the magnet. However... I wanted to know for sure if it could be done, and if I had a quality safe or not. Worst case scenario, perhaps someone might get a laugh out my experience. So... Mechanical is my preference because of this...
