 If you liked Hikaru no Go |  ...then you might like Death Note |
Both are drawn by Takeshi Obata, so it means amazing art. Even if the plots are totally different, in both manga the main characters are guys who have a shinigami/spirit that follow them around.

Both series start with an average boy encountering the sole fantasy element in an otherwise true-to-life setting and being irresistibly drawn into a world in which is allowed to demonstrate his true abilities and judgment. And of course they both have a flair for the dramatic: board games and notebooks have never been so thrilling!

The main characters of both series are followed by a spirit that not everybody can see and gives them a certein power. They are also both students who want to become the best at something (death note being to rule the world). Death note is a more dark story than Hikaru no Go. The art was also done by the same artist, so if you like that you will like it in the other manga too.
