I have a North Face 2-person bag and I absolutely love having the extra space to stretch out. That said, even a quality 2-person bag (I think mine is 20° rated) is not going to be nearly as warm as a single bag or mummy sack. On particularly cold nights, I bring a fleece sleeping bag or blanket into the bag to wrap up in, and I also always have a large comforter to cover the whole bag. With these layers, plus long-johns, socks, a warm long-sleeve, and sometimes gloves and a beanie, I've been comfortable on some pretty cold nights. Sometimes I'll also make a nalgene bottle full of hot herbal tea right before bed and bring that into the bag with me. It'll radiate heat for a long time, and sips of a warm beverage will help as well.

The NorthFace One bag, if it’s still made. Never had a cold night with that one.
