Both are incredibly awesome, but I like Dragonite more, due to its myriad of impressive and badass qualities that I have observed throughout the entire history of the Pokémon series: Its incredibly powerful Hyper Beam when used by Lance in the first two generations; the sheer helplessness its opponents find themselves in when Dragonite used Agility followed by Wrap in Generation I; its access to Horn Drill, the best move ever in Generation II; its access to some similarly awesome moves such as Draco Meteor, Outrage, Superpower and ExtremeSpeed (though Dragonite also had access to ExtremeSpeed in Generation II, this move was quite useless in that generation, especially due to its incompatibility with the incredibly awesome Horn Drill) in Generation IV, and finally, the fact that it got Multiscale, one of the best Abilities ever, as well as being the only Pokémon barring Smeargle that can learn both Hurricane and Thunder, in Generation V. All of the aforementioned serve to make Dragonite remain as my favorite Pokémon ever up to this day.
