Both series primarily feature vampires and Jirou's design is somewhat of a ripoff of Alucard's design in Hellsing. The difference between the two is that Black Blood Brothers focuses much more on the nature of vampires, but I found that the plot within Hellsing and the general action scenes of the series to be much more intriguing then that of Black Blood Brothers. In other words, if you like Black Blood Brothers you may like Hellsing a lot more.

Both feature a ton of action, a lot of fan service, and both share a fairly ridiculous storyline.... Need I say more?

Code Geass: Hangyaku no Lelouch

Both feature similar protagionists and both series have a more thinking and suspense style to it then it does with action scenes. The primary difference between the two is that Code Geass involves politics and warfare where as Death Note is more based on crime and detective work.
