It all depends on what kind of Pokemon you require. Dragalge isn't available in Pokemon X totally, so I think you obtained it from a trade. Looking at its stat, he's really slow, mediocre Sp.Atk, with 97, while a high Sp.Def of 123. Goodra on the other hand is hard to evolve and takes a lot of time, but he's worth it. 100 Atk and 110 Sp.Atk make it a nice mixed attacker, with a pretty good movepool. Tyrantrum evolves earlier at Level 39, is more slow at 71, and a monstrous attack of 121. He's a total physical attacker. Since this is in-game, Hyper Offense is more important, so either Goodra or Tyrantrum. In-game, anything works good. So if you are patient then Goodra, else Tyrantrum is good, but Dragalge the worst choice.
