Is there any way to compare weapons strengths to see which loadout card is better? or will i have to try them all out?
What weapons are better?

If you go to the Barracks and select the Mercs tab, you can view their full profiles and check their loadout cards. Just click them to compare and view weapon stats

The in-game stats are represented by bars, which are hard to compare.
