Pff, Gallit Gun is MILES better than the Kamehameha, if you know how to aim. It charges much faster, uses much less ki, travels faster, hit just a LITTLE bit less. I pretty much never lose a PS to a Kame when I use Gallit for two reasons; A) Gallit charges so fast by the time I am fully charged, he is only halfway up and B) Gallit uses so little ki that if I just play maintainence for a bit while the Kame runs out of ki, I will always have enough ki leftover to push it right back. At SSJ, the Gallit becomes a decent nuker too. Gallit = secksay.
