How come buzzwole is the only good all rounder?

Blaziken and Scizor are pretty good because they can hit with a huge damage if you do right.

Dragonite - You can use one of two paths: one with hyper beam (long ranged) and one with outrage (close combat). Dragonite can paralyze Buzzwole from basic attack. I love it.

Buzzwole is just annoyed me and I bet they can't do without buzzwole's combo that cancels almost all skills most of time.
