First I had issues with the software in both tournaments. Meaning in the first one I used the wrong software and in the second I swtiched to doing it manually, my feeling was adding players later for round 2 might have broken it.
In general there are some things to considder:
You play more players so it’s good for introducing new players into your meta
You are faster in the area you belong to (first or last table, or whatever table based on your deck & skill) so less painful games.
But you play less total games. While when you play 5 rounds of swiss you play 10 games of ANR in this format you will play 7 - 8 games
But I enjoyed it as TO, but don’t know what other think about it.
