So when it comes to ranking the Straw Hat crew members from strongest to weakest there isn't much difference going on in the top 3.
-Luffy
-Zoro
-Sanji

But who is next, who is the 4th, 5th and so on.
Randomly:
-Brook
-Franky
-Usopp
-Chopper
-Nami
-Robin

How would you rank them? Who is the next on the list as the strongest?
My List in order:
-Luffy
-Zoro
-Sanji
-Brook
-Franky
-Robin
-Chopper
-Usopp
-Nami
