TIOLET!
Line is still a projectile weapon, whereas pulse is hitscan. When the first line hits the enemy you've already pumped 10-15 shots into it with the pulse rifle, more than enough to blow off 2 limbs. But yeah, this would only work on PC more or less thanks to mouse aim.
Edit: Not to mention that lines move at a ridiculously slow speed, and are more likely to miss enemies that like to dodge or just move around a lot. With hitscan weapons you don't have to wait for the enemies to line up for you.
