I like the Mauler the most, it's free and semi auto. It's a good option. If u put 1x and ext mags ( from 6 to 10 rounds ) on it u have a decent shotgun for all of your classes. And only for 130 certs...
It depends, if you like to spam and want a weapon that is forgiving when shots are missed in the haste of Cqc, stock mauler with extended mag is your pick. if you are quick to react and prefer one well placed shot, pick jackhammer. DO test it on training area and use trail version before spending your SC/Certs on it.
