I wanted to know which Pokémon was better for Ingame Pokémon White.
well that depends on what your looking for. Overall Braviary is harder to train and has a rather plain move set but in battle they can work for both attack and defense. Archeops on the other hand evolves earlier in leveling has much more variety in its move set and hits harder but it usually isn't in battle very long because of its lower defense and hp. oh and Archeops is available much earlier in the game.
depend, archeops you get it after 2-3 gym and breviary you need to get rufflet and evolve it and rufflet only appear in victory road and the route before
