Should You Choose Spark or Sierra in the Pokemon GO Holiday Part 1 Research?

In Pokémon GO's Holiday Part 1 branching research, trainers face a choice: aid Spark or Sierra. While Niantic's official announcement omits this free research, available December 17th-22nd (9:59 AM local time), the decision impacts your Pokémon catching focus and reward encounters.
Choosing Your Path: Spark or Sierra?
The core difference lies in the Pokémon types: Ice (Spark) or Fire (Sierra). The final reward (Sandygast) remains consistent, but the earlier encounter differs significantly.
