I personally LOVE my side by side one. I have tons of room, in my opinion!
In my old fridge with the freezer on the top it was always sooooooo unorganized and too small in the freezer part! There was never enough room in our freezer for more than a few days worth of meats along with the frozen waffles, nuggets and other boxed items. And no way could I have tons of frozen veggies and fruit on hand! Tons of stuff would expire in the refrigerator because it would get pushed to the back and buried and forgotten!
Pros of my side by side.... the size, I also have a water filter and ice cube maker thingy. The freezer has a bin for storing my bags of frozen veggies and fruits and other bags on the bottom and also has 4 adjustable shelves in it... I took out one since I do not need it. I am also able to fit a large Red Baron Pizza box flat in it with no problems.... I actually have 4 on one shelf now :) And I probably have enough meat in there for atleast 2 weeks(15 packages of meats). Plus frozen bagels, waffles, fish sticks and chicken nuggets and other goodies. I still have a little bit of room left over. I am able to buy tons when it is on sale and freeze it and saves me money in the end!
The fridge has 2 bins for fruits and veggies and a 3rd for meats and cheeses. It has 4 shelves- 1 of them is a shelf that I can make as a half shelf or full so I can fit taller items on that one if I want- have never had to adjust it though except when I was defrosting a turkey one time. I put all my condiments, eggs and what nots on the door- 4 shelves there also. My daughter has a shelf for all of her organic and natural foods. A shelf for water and soda. and I can put 4 gallons of milk and 2 bottles of juice on the top shelf. The bottom shelf is for left overs and my hubbys lunch stuff.
Seriously, mine is HUGE and did not cost me an arm, leg and kidney to get either! Look at the different sizes of the inside and bring a box of the largest item you buy to see if it will fit with no problem. Watch for sales though and price shop!!!!! You might also want to check like Sears Outlet for a great price on which ever one you decide to get. I will personally NEVER go back to a freezer on top!!!
Blessings to you!
