Both great choices. They're pretty similar, neutral, like going straight, and fly pretty driver like. It really comes down to feel. The Axis has a small bead (or maybe its shape just makes it feel that way... it's been a while since I threw the Axis and the Buzzz is no bead and pretty shallow (feels more driver like).
I've thrown both, but not extensively, so I'm sure there are people who will be able to give you more detailed information. But, they fill a similiar (if not the same) role.
Edit: I might as well get off the fence... I preferred the Axis. Nothing against the Buzz, but it felt a little too shallow for me and while both were extremely workable, the Axis was easier to throw dead nuts straight, at least for me.
