Depends on if we're talking singles or doubles. In singles, full stall teams can be good, but individual defensive Pokémon generally don't do much. In doubles, on the other hand, single defensive Pokémon can be very strong, using support moves to buff and heal its ally or debuff and control the enemy. In fact, the most powerful Pokémon in VGC right now is support Incineroar.
