The way I see it stacked up is this.
Jango's Plusses:
1. Missile firing jetpack (1 shot)
2. 2 Blasters
3. Flame thrower
4. Grappling hook
5. Gauntlet blades
6. Traditional hand to hand combat abilities
Maul's Plusses:
1. The Force
2. Double-bladed lightsaber
3. Martial arts abilities
Now, measurably, Maul looks to be screwed, but in the world Lucas has created, I think Jango'd be screwed in the end. The flame thrower could quickly be disabled with the force like Obi-Wan did to Durge in CW, the grappling hook, if Maul keeps his guard up, could be cut down with his saber, as could the blasers, again a-la Obi-Wan v. Durge, and Maul's martial arts skills and speed could dodge the rocket fire, hell Obi-Wan did and he wasn't that much of a speed demon or martial artist, so in the end, like a boxing fight, Maul would wear Jango's resource down, and even if it came down to no weapons for either and Maul could use the force, or even without it, I think martial arts would take traditional fighting.
