This is a debate, not an argument, let's be adults about this. [Insert political joke]

It will work either way, there is no polarity when a circuit is made.

There is polarity before a circuit is made. One wire is live, one wire is a neutral return.

For a basic heater, plugged in one way will have the heating element always live, and the other way it will only be live when it is switched on and a circuit is made.

One is definitely safer than the other.

Almost all devices that switch mains power, have both the live and neutral connected to the switch.
