My wife and I elected to buy the counter depth model, which I believe comes in at approximately 22 cu. ft. We love have the 4-door french door model as we find it easier to organize our freezer. Our prior experience with the traditional french door is that food can get lost and forgotten on the very bottom of the freezer drawer. With this 4-door model, we feel better able to organize our foods. The bottom right door is a flex zone, allowing us to use it for a freezer or other purposes. We currently use it to chill beverages.
I forgot to mention: the showcase door is always a cool feature; my wife insisted on a model with the showcase door. This allows easy access to items (such as my baby's milk bottles) without having to open to whole refrigerator door.
Ultimately, our decision was down to this model and the Samsung 22 cu. ft. counter depth side-by-side refrigerator, which has a full showcase door on the right. Samsung's side-by-side I thought is very sleek and simple with that throwback/nostalgic classic look. Not to mention that it is a couple hundred cheaper than the more modern french door models. However, I found that the width measurements for the freezer of the side-by-side was smaller than the width measurements of the 4-door french door model (though not that much smaller). So we elected to buy this model in case we needed to throw in a turkey that was a few inches fatter. I recommend bringing a measuring tape with you into the store when you're shopping for a refrigerator to measure all of these little nooks and crannies and entryways. Also, with the side-by-side, you wouldn't be able to slide it trays of food or something that is pretty lengthy/wide, like a box of pizza. With the 4-door french model, you can easier put a tray or whatever.
Though the counter depth model sits very flush with our counters in our kitchen, you are paying more for less space, which seems very counter intuitive. However, if you do not have a lot of space in front of the refrigerator or if you just want that clean/flush look, you can try to justify in your mind that the extra price is worth it. Given the smaller size, there are some shelving areas on the inside side of the left door of refrigerator door that are so small that not many items fit there. I've found myself placing my son's cheese singles in these areas. If you see the model, you'll know what I'm talking about.
This model itself isn't that noisy, but you can notice it if you pay attention. With the noise pollution outside of my house, the dishwasher running, washer/dryer running, and screaming kids, I don't pay much attention to or notice the noise. I do not know how this compares to other models.
The ice maker and water dispenser work perfectly. I am curious if the ice maker/storage is smaller than the regular-sized refrigerator. This may be something you inquire about should you be interested in this model. After they first install the refrigerator, they tell you to dump the first batch of ice and the first 2 gallons or so of water to clear out the sediment in your water line. When is emptied my ice maker, I got the impression that there wasn't a whole lot of ice to dump out; so perhaps the storage is smaller? I haven't confirmed this.
Overall, I am very satisfied with this model. It is very sleek and modern looking; I purchased the stainless steel model. I believe they make a black stainless steel model for a higher price tag. I would have preferred the color scheme but couldn't justify paying the additional money. I was going to give it a 4-star for sizing issues. However, I (consciously) paid more for the smaller size for that more flush look. I am not going to dock points based on sizing issues that I elected to buy. For a counter-depth refrigerator, it's pretty sick.
