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 crucial decision: assist Spark or Sierra. This guide clarifies the choice, focusing on reward encounters and Pokémon types. The event, running December 17th to December 22nd at 9:59 AM local time, offers a free research path with three stages. After the initial tasks, players choose their allegiance.
