Which storage method is more secure?

Standard stack on cabinet vs wall mounted lock?

I have two cabinets but will just use those for ammo.
I swear a prybar will open the cabinet.

I see a lot of security devices as child resistant and theft deterrents. Pry bar hell, a well equipped thief will have battery operated grinders and drills.

I like keeping my firearms covered so nothing can fall down the barrel .
