I agree. Though I voted for WB, since he is dead. To respect the past ones or sth.. xD
I also voted for WB to respect a great man.
Other options for me were Dragon and Zoro, but Dragon didn't participate in an action for a while and Zoro was inpresive, but not as as much as Whitebeard lately and all his presense and fights in a War were epic and of course his final speech and his death. The impact of this character on the story is second only to Roger.
