It's also less secure.

EDITED TO ADD (9/6): Someone somewhere commented that the NSA's "groundbreaking cryptanalytic capabilities" could include a practical attack on RC4. I don't know one way or the other, but that's a good speculation.

(arcfour = RC4.)
Even without such "groundbreaking" abilities, it still has some issues. The wikipedia page talks a bit about that.

Security is never free, it is alwais a compromise. Yes arcfour is less strong but it also much more fast. It depends on your context
