The other thing to take into consideration is the stats that you will have to train. Dexterity is a must for any good player, so having Dexterity as a required stat is good. Resistance has to be trained minimally, but is not a required stat for any weapon, so it is moot. The question is strength over accuracy. Strength provides less encumbrance, but I don't know what else Accuracy does. Either way, if you choose Shotgun or SBM, you'll have to train both, so keep that in mind.
