GENESIS vs. Death Star

Gundam SEED's Genesis (Gamma Emission by Nuclear Explosion Stimulate Inducing System):
It harnesses nuclear explosions, to create a highly powerful Gamma Laser, capable of destroying all life on a planet. And bodies near the beam inflate until they explode.
Star Wars' Death Star:
A gigantic space station, with the power to destroy entire planets. Not much else needs to be said.
Which one wins in a quick-draw? (Because only one shot is needed either way)
I say GENESIS. It doesn't take as long to prepare a shot. It's Phase Shift doesn't really matter, PS armor isn't immune to beam weapons. But the Mirage Colloid might give it the advantage, if the Empire doesn't know where to shoot.
