Definitely a black hole.
As a supernova star starts to die, it begins collapsing upon itself because its external forces are overcome by its gravitational ones. This forms an extremely dense neutron star which contains so much mass in such a relatively small space, its gravitational forces become extraordinarily large. As the neutron star continues to collapse it becomes an infinitely dense black hole where light cannot escape, mass becomes infinite, and time nearly comes to a complete stop.
You tell me, what's more powerful?

Depends on what you mean by powerful. Gravitationally a Black Hole is more powerful. In your talking electromagnetic energy then I would have to say the black hole as well. Some people might say that a star produces more EM energy, but I tend to disagree. A black hole produces the energy, but because the escape velocity from a black hole is faster then the speed of light, that EM energy cannot escape from the object.

More powerful for what?
In general, astronomers measure the luminosity with units of power. Since a black hole is, well... black, then it has no luminosity. Then any star that shines is more powerful.
However, matter that falls into a black hole can emit a lot of energy as it is ripped apart by the strong tidal forces near the black hole. Very large black holes (like the ones at the centre of galaxies) with masses of a million suns can rip matter apart with lots of force, giving very strong energy outputs (sometimes outshining entire galaxies, as in Seyfert galaxies). The energy does not come from the black hole itself, but the black hole is responsible for it.
The most massive stars can only reach a hundred or so solar masses. They are puny compared to very large black holes.

It would depend on the black hole and the star. All stars are not the same size and neither are all black holes.

A black hole!

It depends on the type of star. If the star is sufficiently massive or compressible, it may collapse to a black hole. If it is less massive or made of stiffer material, its fate is different: it may become a white dwarf or a neutron star.

balck hole, it can suck in a star
