I prefer single-team season replays and tournaments because I can complete them quicker than multi-team season replays.
Both are excellent in their own ways, however, I prefer iScore. There are two major scoring apps, GameChanger and iScore. The pace of the calculating allows them to see streaks and tendencies in their games, which makes them feel connected to the history of their projects. However, there are others, myself included, who want something a bit quicker and simpler, that still can provide that connection if it’s desired. Also, they love the calculator and the worksheet when figuring out statistics for their replays. The nostalgia of it takes them back to when they were kids first learning the great game of baseball. There are many who play APBA that love pencil and paper score keeping.
