I like all three in General. All very creative Pokemon by name, looks and coolness. In TCG, I would go for Zapdos, because it has the best cards in various sets so far, IMO. In Pokemon RPG, I like Zapdos. It's a killer to Blissey with Metal Sound when combined with Dugtrio, it kills DD-ers using T-Wave, and has great Stats all way round. Articuno comes next for me. It has supportive moves such as Reflect, but Moltres gets Morning Sun and WoW.
