I think the best thing to think about, it what is most likely to happen, and what will you want on that occasion.
For me, in my location, my most likely disaster is getting snowed in for a week, without power. So, in those circumstances, a way to heat up food is essential, and if I didn't already have a gas stove, I would buy one.
I always have a week or so of food stored in winter, as experience has shown, that in the above scenario, unless you are in a populated area, no help is coming from the council.
I have prioritised the sort of easy food that the kids will want to eat - pot noodles, pasta, baked beans, soup, rice & tins of curry/meatballs, with tinned fruit and puddings, and a secret box of quality street. It's water that is the hardest thing - need a lot to cook pasta etc.
If for some reason, I couldn't have a gas stove, I'd make sure the freezer was full of bread, and have a lot of cheese in at all times, plus peanut butter, nutella, tinned fish.
