The base stats on the SR and CD are similar, so you should look at the vendor rolls for what suits you. The Crucible version has a pretty nice roll. They are both in the higher rof/lower damage category than the Badger and Gheleon's Demise types. Both types can be good in their own way; I like the high damage ones for things like higher level Hobgoblins where you can shut them down in one shot before they flame shield. I have a CD from a drop with Final Round, High Caliber/Hammer Forged/Armor Piercing, Firefly and it is very good. I don't miss the Sat Rap Outlaw perk that much because it has a pretty good reload out of the box. If I was buy one, though it would be Sat Rap with the roll it has.
