Views on junglers patch 5.6

just wanted some advice on jungling after patch 5.6.. the main people coming to my mind for tanky junglers are hecarim vi reksai or gragas... even though gragas is not a very popular pick just wanted to know which champion should i pick so that my interest as a jungler stay alive...i tried vi and hecarim (free for the week) and found vi to be a better pick.. i need views on reksai vs vi vs gragas as a jungler.... Pants are dragon a pretty decent youtuber put vi on the 7th position grags on 3rd and rek sai on first position in his best junglers patch 5.6 video... AND NOW I AM CONFUSED HELP ME !!!!!!! RITO PLS!!

EDIT: AFTER SEEING THE POSTS ABOUT VI OR REKSAI (WHICH WERE VERY OLD) I NEED AN ANSWER AFTER CONSIDERING BOTH HAVE BEEN NERFED AND PLEASE INCLUDE HECARIM ALSO IN THE DISCUSSION

IN SHORT WHO HOLDS THE BEST JUNGLER AWARD IS IT REKSAI VI HECARIM OR GRAGAS
