I actually like Braviary better than Barujina, though Barujiina is pretty cool too! (I used to dislike it, now I'm at a pretty much neutral/like.) I do want to train it someday, hrr.
But hey, Wargle isn't overrated! Saying that is basically saying birds like Staraptor are overrated too. I'd actually say Umbreons are overrated... (50,000+ deviations! More than all of the other Eeveelutions!)
I have no idea... I'd say the two birds are actually pretty equal to each other, but that's my opinion. It kinda depends on what you call overrated... things I think fit into that category are "OVER 9,000!" and "Doctor Octagonapus" and "I like trains" and such. But then again, those are internet fads...
They could actually both be "AHMEGAHSIWANTITSSSOBAD" in terms of games, since you get both of their pre-evos really late in the main story, and they evolve at high levels.
