Both safes are junk unless you get their high end models.
It really depends on what you're going to store in it and why.

If you're just trying to prevent your children from messing with your guns, any steel box that locks will be good enough.

If you're trying to keep the bad guys out, you need a safe that is tough enough to withstand hand tools like pry-bars and axes.

Body Steel must be thicker than 11 Ga because that's the point at which an axe will no longer rip a hole right through the side.

The door should be plate steel and be thicker than 1/4 inch.. Roll formed doors are junk and doors of thin steel can bend and twist enough to pry open.

Fire protection is up to you and will greatly depend on what you put in the safe and where the safe is located.

I would STRONGLY suggest getting a STURDY SAFE CO. brand.. They're ugly as my dogs a$$ but far more functional than any of the others.
