I used to cook over a fire 100% of the time.  Never could understand why anyone would want to pack in heavy stoves and fuel when cooking over a fire is free and saves a lot of weight in the pack.

Then I finally had to make a trip under a fire ban.  Brought along an old "green suitcase", the trusty Coleman two-burner stove.  My eyes were opened by the experience.  Yes, it was more weight and bulk in the packs but I found that cooking was much quicker and easier, plus the cleanup time was greatly reduced.  After that trip, I resoved to stay with stove cooking.  I did quickly realize that two single-burners were much lighter to pack and provided much better heat control than the old suitcase so that's what I use now (and sometimes even a 3rd for larger groups).

I still use a fire for foil-baked trout or the rare trips where I am base-camping and I bring a reflector oven, but that's about it.
