Although, Championship is more politically correct, a championship is normally for the best. Since you don't need to have won a regional, chairman's or anything like that, then it isn't of the best. If you had to win an award to make it to the Championships then it would be called Championships.

Plus it sounds funny when you say that someone's the championship champions.

Worlds would make the most sense.

I just call it Atlanta.
