Strongest Guardian

Who are the strongest Vongola tenth gen guardians in order?

To me it's:

1. Mukuro
2. Hibari
3. Gokudera
4. Yamamoto
5. Ryohei
6. Lambo.

Mukuro is first because he seems to have the widest range of abilities, and he already beat Hibari during the Kokuyo arc. I'm not really counting Chrome but if I did, she would be right below Ryohei.

If this was the future, I would switch Gokudera's and Hibari's places; even though, Hibari is considered the strongest, there's a reason Gokudera's the right and man.
