King of the Hill Game Options Scoring Style?

Can someone explain the different options for King of the Hill Scoring Style? They are: Score One, Everyone Counts, and Team Difference. Thank you.

Everyone Counts - You get +1 point for every team mate in the hill. So if you have three teammates in the hill at any point, you’ll get +3 each second.

Score One - You get +1 point, regardless of how many people are in the hill on your team.

Team Difference - Let’s say there are two red team members in the hill, and one blue person, the red team will get one point, while blue team will get none.

If there are two of each time in the hill, then both sides get no points.
