I switched between the 2 to start off. In the beginning of the game I always had it on Active when I faced regular battles, but with boss battles I turned "Wait" on while I shuffled through the commands of my characters.
However, when I got familiar with the game, and where everything was at in my commands menu, I turned on Active all the time. Also, when I mastered the art of using Gambits for my characters, Active battle became the ultimate way to go. Battles went fast and easy and made gameplay quite convenient.

If it wasn't for this thread, I probably would have never known.
