A safe is simply a means to buy time for your valuables; the better the safe, the more time you can buy. I look at it as an investment so bought the most capable safe I can afford (my next home will likely have a vault built into the structure itself).
Additionally, a safe should be only one layer of a multi-layer security and defense framework which should also include an alarm with 24/7 monitoring, visible and hidden security cameras with phone app so you can see near-real time what’s going on and, when possible, a network of observant trustworthy neighbors that keep an eye out for each other, reporting suspicious activity and persons as soon as they see it. If someone does break in, they won’t have enough time to breach a well made safe if all of the above also applies.
