The shape of your refrigerator can have a significant impact on your daily cooking routine. To have a reasonable grasp as to how French doors and side-by-sides relate, let's concentrate on two GE versions.
From the cost point of view, the $700 difference between a fairly mediocre GE side-by-side and a fairly mediocre GE French door model is also rather common. Because French door refrigerators are more fashionable, you should expect to pay extra for them, particularly if you want anything elevated.
Of course, the side-by-side has more freezer space. Furthermore, the design's verticality provides many shelves for simpler management. Side-by-side and French door refrigerators are both good choices for small kitchens because neither need you to unlock the door that spans the entire width of the refrigerator.
Although performance varies by manufacturer and type, the analysis of the two GE refrigerators gives you a good understanding of what to expect in the two groups. Well over course of five years of testing refrigerators, side-by-side refrigerators have suffered as much as any other group in my cooling testing. Because of their design, French doors tend to perform relatively better, but don't expect a significant increase in cooling power. Look for versions that have been evaluated by sites, which put each model through a thorough cooling test.
