I agree that objectives are more fun than score targets. And I think you can make a strong argument that this is also friendlier for casual players because of the way that it strips any game knowledge advantages out of the equation.

When shooting for a target score you give clear advantage to people who know the most efficient way to score points on a particular game. When shooting for a specific goal everyone is in the same boat with only technical skill to separate them.

Plus it is more fun for the group to watch players all trying to complete the same objective. For example, the goal of lighting both stars in TAF (orbit > million plus ramp) is thrilling to watch a player make repeated attempts, and the pressure associated with that. In a score-based pingolf TAF just ends up being a race to Multiball, pretty much the same as any regular game.
