I think Boba is better just because he obviously has the same physical tools and he has the benefit of Jango teaching him everything he knows. Plus Boba could pick up extra knowledge along the way. The only thing that makes me question Boba is that he was killed by a blind Han Solo and Jango survivded a battle with OB1 and was killed by the 2nd greatest Jedi Master.
Jango was a Wuss, Boba was a victim...
of a sucky plot line.
Jango had cool armor. But he used a woman (no offense to the ladies) to do his work. Got high kicked and defeated by Obi-Wan (Ewan is not very imposing by-the-way...looks too much like Jesus) on the landing pad. Missed out on killing Obi in the asteroid field while throwing a ridiculous amount of firepower at him. He had to have destroyer droids back him up to capture Ani-wuss. He killed only one Jedi, got trampled by the Reek...and got Maced...yeah baby, you know what I mean! And he looks like a hoodlum thug...and, he sounds like he needs to be in some New Zealand pub chugging Foster's Lager. I was expecting some Arian-Nazi sort (Jude Law after 6 months with Arnold Schwarzenegger in the gym would have been good - like what they did with Tobey MacGuire in Spiderman).
Boba was cool. We have to remember the same guy that put 3 foot teddy bears with slingshots against 1.8 meter tall, armored legions of Palpi's best troops with mechanized war machines...wrote the plotline and another flaw (among so many) is Boba was neutralized by a blind, physically ill Han in an accidental jabbing of the Jet Pack. In the pit...why not just hose the throut down with some flame, or use that small blaster under his arm pit, or knee darts...lame. Yeah, I know, there is a book and he escaped...but Lucas made him dead.
Jango should have just been slaughtering Jedi for about 5 minutes, and then have Mace save the day...that would have been cool.
