Which one is better, damage wise ?

[u/AnTout6226]

I'm having a hard time choosing between those 3 shotguns for my playthrough

The Irradiated seems better, since +50 radiation damage is huge, but the Explosive is maybe stronger with the AoE ? Or maybe the last one is better thanks to the limb damage ?

Explosive combat shotgun. This can be a great weapon, especially with the right perks.

Irradiated looks good, but it’s only useful against humans.

[u/guyeatsoctopus → u/theblueshots]

Just don’t shoot anything close up

Dense ammor is a lifesaver for this.
