Samsung is a huge company with lots of products, so naturally some will be better than others. When I say "huge" it's hard to imagine how big they really are, as there are few companies on the planet as big. And family-owned, too.
If you live in Korea, chances are your refrigerator is a Samsung, and if you go to a hospital it'll likely be a Samsung hospital and you'll pay for the visit via your Samsung insurance policy. Visit Korea and you may go to one of the Samsung theme parks.
