Jango Fett was really cool, he was Mandalor briefly, he became the template for the clone army, best bounty hunter in the galaxy but after reading the expanded universe you will see that Bobba reaches a whole different level.
He was running around with a bounty hunter gang as a kid, became the best bounty hunter in the galaxy, he escaped a Sarlacc pit, marriedSintas Vel(One of the coolest female bounty hunters around), also became Mandalore and trained Jedi masters.

Although now that disney has brought it I dont think any of it is cannon anymore.
