Question for Model UNers

I’m really curious, why does MUN look so good on a college application?
Is it because MUN requires the students to speak and do academic writing?
I’ve never done MUN before, so I don’t really know what goes on there, but it sounds pretty fun.

Cuz it has everything that colleges love: team-building/teamwork, research work, public speaking, critical thinking, diplomacy, etc. Most other activities will only have a few important qualities, not all of them together. On top of that MUN is extremely competitive and prestigious, which colleges of the same nature love
