Holiday Research: Spark or Sierra, the Better Choice

In Pokémon GO's Holiday Part 1 branching research, trainers face a crucial decision: aid Spark or Sierra. While Niantic's official announcement omits details on this free event research (available December 17th - 22nd, 9:59 AM local time), the choice impacts the Pokémon encountered.

This three-part research path requires a selection after the initial tasks. Choosing Spark or Sierra primarily affects the Pokémon type you'll focus on and the reward encounter.

Note that Part 3 rewards (including the Sandygast encounter) remain consistent regardless of your choice. The decision boils down to preferred Vulpix variant and desired Pokémon type focus during the Holiday Part 1 event.
