I'll answer your question with a question: Which do you need more - narrow vertical storage space for flat items (e.g., cutting boards or baking sheets or even a pullout broom closet), or fridge space?

Have you examined the required clearances for the doors of the fridges you're considering? The filler space to the right of the fridge looks too narrow for a lot of fridges. (Mine is a Samsung and requires 16" for me to be able to open the door and extend all drawers.)

Remember that the interior pullout construction will take up room, reducing the actual shelf space. A metal wire pullout will perhaps have more usable shelf space than a wooden one.

In my small kitchen any size of storage is good storage. I would love to have a tall narrow pullout for my broom and dustpan.

My lower cabinet pullout in a 9" space is made of wood and has only 5" wide shelf space. I use it for spices, but my flat pans could go there, and also could have boxed or canned goods.

So, again, which do you need more? Do you have a very large family that needs lots of refrigerator room?
