The extra troops would make it an interesting choice over the M-3. The M-3 is much more survivable because it is harder to see. A C-47 can bee seen outside of icon range but with the advantage of extra troops, it might see more use. If it can get to town alive, the extra troops are going to be harder to kill.
It isn't any different than weighing the options between planes or vehicles for your sortie. Right now, the M-3 (because of relative invisibility) has made the C-47 obsolete. The only reason to ever take one is if there is no spawn to the enemy base.
