The 'Fuzzy Fighter' Special Research ticket priced at $8 offers players the chance to obtain a second Kubfu, which is valuable for collectors. It also includes rewards like three Rare Candies and encounters with various Pokémon. However, the decision to purchase the ticket depends on individual player priorities, especially regarding the future potential of Kubfu with Dynamax/Gigantamax capabilities, thus making it a complicated decision for players focused on max battles.
If you really want a second Kubfu, then yes, it could be worth it, but there are a lot of unknown variables in regards to Kubfu's future with Gigantamax.
Buying the pass from the webstore gives you three Rare Candies and three Max Revives, in addition to encounters with various Pokémon.
