Yet again here we go in the Fett vs. Fett thing. You know what I found disappointing about Jango Fett that he didn't get to kick more ass in the movies,the same disappointment I found in Boba Fett. Especially if anybody ever saw Once were warriors,you know T.M. is great in a brawl scene.
By the way,being a clone does not mean that you end up the same weight and build. If you took a guy and trained him to be a runner, he would be lean and sinewy. If you took the same guy and trained him to be a body builder he would be muscular and heavy. If you trained him to be a tri-athelete he would come out somewhere in between.
I've never heard of this so called comic Jango Fett versus the Razor Eaters,not to mention comics are not considered canon. No matter how much some of them are really great, most are crap.
Jango never says Boba is stronger than him,he says he's a better shot than he was as a boy. That's in the AOTC novel,look it up if you don't believe me. Of Course Boba was trained as a warrior from the get go,Jango started as a farmboy (shades of Luke Skywalker).
Jango was never the Mandalore, and Boba Fett became the Mandalore under duress. Both ended up leading mandos out of duty not by choice. By the way,not all the Mandos under Jango command die,because Dooku is interrogating one, also Jango was shot out of the sky and still went back to help his men. He STAYED with them,FOUGHT with them,that is what a commander should do. He is by no means a poor leader. Hell,in the end he even avenged them.
Jango and Boba also have different fighting styles, and that effects the way they are built.
Boba Fett prefers speed,stealth, and distance (his choice of less leg armor, a rifle, and leaner build suggest this). Jango is a much more physical,in your face,street fighting man (his heavier style armor,short range pistols,and heavier build...not to mention the duke out with Obi-Wan). This part is of course just my speculation.....
Boba and Jango like any other son and father share alot of traits,but just because they are clones does not mean they are exact duplicates. Even the clone troopers start to act differently as they experience different things.
People,Fetts included, are more than the sum of their parts.
This was brought up in another thread, Slave 1. Jango had siesmic detonators, Boba has Ion cannons. Destroy Utterly. Immobilize and Capture. Jango Fett obviously has some anger managment problems.
