Falco is the best of the three. Fox and Wolf have just steadily been getting worse as time goes on and people learn...
In a nutshell, he can handle himself at practically any distance and has too many stupid tricks up his sleeve. However, he's got his share of hard match-ups, mainly Meta Knight, Snake, Marth, and Pikachu.
thread shoulda been closed after first post said falco, there's not even a comparison/debate about it
falco's chain spike alone wrecks the match up, he has other things but this alone just makes it rediculous
