I find Fossil[1] to be best DVCS for individuals and small teams. It's like a complete github on your computer. Some salient features -

a. It has a Wiki

b. It has bug tracking

c. It has it's own server

d. It's got a nice and simple web interface. Especially when it visualizes the different branches[2]

e. It's a single file executable across all different operating systems.

f. The Autosync feature[3], which is on by default is, in my opinion, makes version management dead simple. (no pushing and pulling!). This feature by itself makes starting with DVCS really easy.
