In Asia from what I heard Panasonic is the best (Mitsubishi on the other hand isn't). In the US from what I understand stay away from Samsung, LG is slightly better but still not the same as the typical American brands.
My GE Profile is going on 25, but base on the flooring it did have a leak in the past. Since I disconnect the water line anyways it doesn't bother me at all. I heard Haier / GE is good but LOUD from people I know in China, they like to stick to low tech boring and loud design, because a lot of their customers are peasants and shop on price and reliability (but not comfort and aesthetic).
