There's really no wrong way to use a margarita pool

The biggest difference IMO is that it is easier to determine a good strategy in LoW. In Fresco, everyone seems to be competing for essentially the same things throughout the game. In LoW it felt like we were competing for similar but not entirely the same things.
So far I prefer LoW because I can more easily determine why I did well or poorly at the end of the game.
