A handful of years ago, the Hapkido section here essentially imploded with arguments over what real Hapkido is, its origins and who trained with what master.
Frankly, the question over who is the best hapkido master in the world for you can only be answered by you. My advice for a high-ranking martial artist with multiple dojangs at his fingertips and no restrictions to travel and investigate would be exactly the same for the mignon who has not a penny but needs self-defense training: go out and find what speaks to you.
Perhaps if you could narrow it down to a lineage you prefer, then you can follow the chain of command on upward and go from there.
I invite you to peruse the much, much older threads in this forum to research hapkido origins and the controversies perceived as a result.
Peace.
