Judge competitions have a judge, or several judges, who decide on who wins the competition.

Bigger competitions are about doing something bigger than the other guy. It could be a a bigger volume, size, or amount.

Endurance competitions entail lasting longer than the other guy. They include competitions when the other guy might get caught or break a rule first, as they didn't endure longer.

Event competitions are more like a sport, where a winner gets crowned based on an event or series of events that take place, crowning the best at that event.
