Plasma or Melta?

Melta has one more and more debates than plasma has ever dreamed of winning, and with that in mind, I side with plasma. Plasma may be more expensive, it may be weaker, and it may have a slight chance of killing the user. SO? plasma is a 24 inch range weapon, that can pierce space marine armor, and wounds them on a 2+ I'm sold. Not only am I sold, but I'll effin buy it all. In fact, in each squad for two platoons I have I have a plasmagun, and a plasmapistol for a total of 12 plasma weapons, at close range, thats 18 plasma shots. Combine that with the 6 rocket launchers, and in six squads I'm gettin 24 ap 3 or lower shots, so space marines, you can suck it, no saves. Melta, you don't get that, melta you get 6 shots to my 18, and with less range. while you may be str 10, I'll stick with my plasma, and as far as points go, I don't mind, they miss 50% of the time, so more shots is worth the higher price. And as far as the dying goes, theres a 12% chance a guardsmen will die everytime they fire one of the guns, so what? they're guardsmen, there's more. so melta, have your overpowered BS :p
