I'm having a blast downloading One Piece's new episodes for the Fishman Island arc and streaming Hunter X Hunter 2011 episodes. Obviously, I intend to keep the One Piece episodes while I only want to watch the Hunter X Hunter 2011 episodes.

That does not reflect my personal preference between the two - in fact, I would have a hard time comparing One Piece to Hunter X Hunter. It's just that One Piece has finally moved on to the point where the Mugiwara crew finally get back together...
