That which does not kill you makes you stronger.

a couple of ways to compare.
1. if you have the patience you can read the individual weapons in components.txt

2. there is a list in the game...go to create a ship...when the new screen comes up there is a button on the lower right side called weapons report that will display damages for each weapon that you have researched...to get the entire list create a new game and give all techs to yourself.
