I would have to say that the safety and security levels in a particular bank's vaults and security deposit boxes are much higher and much better than any of your own safes in your house.
This is the because the overall safety and security in any financial institutions is a lot higher and a lot better than any generic safes in any households.
What this means is that thieves and robbers have a much harder, more difficult, and tougher time of breaking into the vaults and security deposit boxes in the average bank, than in your average generic safes in your average household.
I always prefer to keep/ store/ deposit all of my money and all of my different valuables, such as jewelry, inside a bank's vaults and security deposit boxes instead of placing them inside any general safes in my house.
I do not like to get robbed nor stolen by any crooks.
The banks are always well-guarded by professional security guards 24 hours a day, 7 days a week.
The security in most banks is always a lot tighter than the security in your average household.
