What’s your favorite tournament format: knockout, league, Swiss or king of the court?

We’re building MECCI around different tournament formats: knockouts, championships, Swiss tournaments and American-style tournaments like king of the court.

Each format creates a very different experience.

Knockouts are simple and exciting, but players can be eliminated quickly.
Leagues are fairer, but require more time.
Swiss formats work well when you want balanced matchups.
King of the court is great for fast, social and dynamic sessions.

For people who play or organize amateur sports tournaments: which format do you prefer, and why?
