What Role is the best to play?

In the next little while I will be posting about the roles in the 4th Edition Dungeons & Dragons.  I will be stating some of the best qualities; and defending why every role is important in the dynamics of this new gaming system.  As much as some of you readers out there do not like the system or even refuse to play it, it is a great system.  I find combat is simple (yet somewhat slow at higher levels), the roleplaying potential has improved, and the organization and support from WotC is fantastic.  I will be highlighting every role in the game and giving my reasons why every role has great potential.
