trekkie will say phaser > laser.

In Star Trek, phasers are fictional weapons that fire a beam of energy, often depicted as a stream of particles, while lasers are real-world devices that emit coherent light beams.

In the show, phasers are used to stun, heat, or even disintegrate targets, and can be set to disrupt nuclear reactions. Lasers, while also capable of causing damage, primarily operate on the principle of light amplification.
