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.

But again if you need effectiveness well then yea you can review the stats

The phased polaron beam is almost pure liquid murder against AI opponents. The ability to skip normal shields is great, and the AI won't respond with any sort of good plan.
