Best one I played in was one where the director pulled names and assigned matches per week. Players were responsible for scheduling the matches on their own within the week. The result was very few forfeits (you felt compelled to play once per week) and an end result of an accurate ladder. He was good about picking good matchups.
Ones that aren't so good are the ones where you sign up and play as much or little as you want. Those end up with some players playing a ton, some playing a few, and others that don't play at all. Result is a lopsided ladder with mixed reviews. I was one that played a ton, but the I played multiple times against...others that wanted to play a ton.
My 2 cents/conclusion...the more effort the organizer does in getting people to play, the more people will like it.
