I agree with exp626mom, I really depends on how you will use your room and the resort. Some of the moderates have sit down restaurant, which can be relaxing...the slightly larger room may be more comfortable for you.
Deluxe resorts have even larger rooms, and larger beds, and usually have several choices of restaurants.
Values, of course, have a food court. I stay at POP on night last month. WHile I usually am not a fod court type person, I found the one at POP (and presumably the ones at All Stas as well) to be very nice, reasonable (by Disney standard), and it had a very nice selection of items. The beds were comfy. The room was clean. I found POP to be very nice resort, nothing "overly fancy" but certainly comfortable.
You really have to look at what you expect from your resort, and the amenities (is a pool slide important to you, a sit-down restaurant, etc) to make an informed decision about where to stay.
