Is there any difference from one another? I keep hearing that using chargers is absolutely a no-go and that power supplies are much safer and better overall. Do you guys confirm this?
Thanks in advance.

Not all USB power supplies are rated for the current the rpi requires (i forget the number off hand). Anecdotally I had nothing but trouble using a name brand charger supposedly rated for the correct current, which disappeared the instant I switched to a $15 power supply specifically sold for rpi.
For the minor cost and potential headaches of brownouts and unexpected shutdowns, and given that you are asking the question, I would absolutely go with one made for an rpi.
The general difference is, a charger will try to keep the current constant and therefore slightly vary the voltage which may harm the equipment when used as a power supply. A dedicated power supply will try to keep the voltage constant, i.e. independent of the current the hardware is taking.
