It is hard to give you an answer considering that you haven't stated any perks on either weapon. Random drops have random perks. Having a field scout on either gun puts it ahead. The fact that Devil you don't only has a 5 round mag, it would need an unbelievable roll for me to consider it. I actually have one that had a great roll, and it still holds nothing to my TFWPKY 1969, and that holds nothing compared to my Word of Crota. Rule of thumb, go for high impact, double digit rounds in the mag or the closet thing to it.
