It’s like a house with one door too many. I recommend a 2 door fridge because it is simpler. One door for the freezer and one for the fridge. The argument could be that if you are in a habit of storing a lot of food for consumption at a later date then you would need the third compartment for such storage. In my opinion you could well use a seperate deep freezer. The advantage with a two door is that there are only two compartments to clean and you tend to keep only things which you really need. You need more space buy a bigger two door!
