You fail to remember Draco, that Boba to had a daughter and was also putting her in considerable danger. Although it is true that Jango seemed somewhat easy to kill, He taught Boba most of his skills. Boba conectrates on stealth, Jango has more of a * Get off you're butt and Kill that worthless dikut'la * edge. But then again, it's true. Boba did grow up to be more ruthless than his Father, and survived the Sarlaac. But no without cost, it still caused him physical damage that are likely to slow his reactions. As you age you're reactions to things are fading as well. Jango was old, so there probally is a difference. When he was young his reactions were at there peak. As he got older..you get the picture. And if his jetpack haden't gone KABOOM!! he probally would've wiped the planet of Mace Windu. Also it seemed that Mace knew where to kill Jango since Mace tried to kill Boba in the series, using a lightsaber. But Boba Survived. Jango was sliced at the neck so...Bye bye Jango. Ironic that Boba survived a Blow to the head. Considering that Jango taught the Clones how to fight, they were able to kill Jedi. True it was from a distance, but remember. The Clones were made to be less indepenent than the origanal host ( Jango) So basically saying that Jango taught his Clones his habit of Killing Jedi, and teaching his son. The Rest of Boba's talent is probally hard earned skill. After Jango was killed. * Soon all that will remain is the heritage and armor upon a man to easily slain by Jedi * ( Kreia, KOTOR II ) I'm not saying that Boba is less than Jango. I think they are both rightfully able to be called Fetts.
Of course that's my two cents..
