Equalized defense against Gauss and Pulse in most places to let them stand on their own. Basically, if you want to see how much damage each weapon does against each level of defense (and are prepared for an excel file most daunting), PM me. But otherwise, just take this to heart:
Pulse is better than Gauss against Very Light, Light, and (barely) Medium Armor.
Gauss is better than Pulse against Heavy and Superheavy Armor.
Piercing Weapons like Sniper Rifle variants are better against heavier armor, and Spread Weapons like machine guns are better against lighter armor. Rifles are kind of in between, so you whether you use Pulse or Gauss against Medium Armor, it doesn't make a big difference.
Edit: Gauss is better for Piercing Weapons and Pulse is better for Spread Weapons usually.
Just keep those things in mind. Example: Soon I'll be posting the pirate factions, so say, if we're going up against 'Faction X' we'd know that they use lighter armors so Pulse is probably the mainstay of our weaponry for that battle, though you're free to choose whatever.
