That depends. The black star dragon balls can do more, but they have consequences. They spread across the entire galaxy after the wish is made, and if they're not returned to the planet that the wish was made on by 1 years time that planet is destroyed. However, they can kill people, unlike the red star balls. The red star dragon balls cannot kill people, but they only go across the planet, not the galaxy. Then there are even more sets, like the namek dragon balls, the old earth dragon balls (made by kame), and the new earth dragon balls (made by dende.)
Red Dragon Archfiend Assault Mode clearly says it destroys all 'other' monsters, so will not destroy itself.
