I guess it depends on the situation and how far along. If the meal is just barely starting and I know there's probably some willing subby prey around the corner, I might go for the easier meal.
But if I've already got them partway in my jaws, they're going down the hatch one way or another. There are plenty of ways to deal with prey like that, such as tying the limbs or using gravity, my arms, and my gullet all together. And sometimes all that struggling means a feeling of deeper satisfaction when I'm patting my full belly later. ;)
