We used to cook on the fire all of the time, but we used to break camp and move every day, paddle a lot farther, portage a lot longer, and do everything a lot more energetically than we do now.

There are only two of us. One small stove is fine for our simple meals, and it is a great convenience. If clean firewood is readily available (read that: no pine), we will cook on the fire. And if we feel like bothering. But now, if we don't feel like bothering, we use the stove. In the morning I like to get up really early and have a quick cup of coffee even before the fire is getting going anyway.
We will often build a pine fire, even with just twigs and the little stuff that accumulates around the campsite, for our morning warm-up fire, or our evening campfire to sit around and enjoy. Toast a few marshmallows.
I think we probably are in the 50-50 group, but more and more we are tending to do our cooking on the stove and save the fire for atmosphere.
I don't remember the big suitcase Coleman stove fondly. Can't tell you what our little tiny stove now is called, but it is small and lightweight, you don't have to use a match to light it, and I like it a lot. When I bake on it I use a diffuser and my small Jello-mold oven, and create some tasty treats.
