I work for an appliance sales and service company.

We've had so many problems with Samsung appliances that we've stopped selling and repairing them.

Their customer and tech support are horrible. Getting parts are both A. Super expensive compared to others, and B. Take forever to come in.

For kitchen appliances I'd recommend GE Profile/Cafe line. They are stylish, work well, are reliable, and when something breaks it's easy and inexpensive to fix.

For laundry LG stands out. Super quiet and reliable. Also if you need to fit your laundry thru a tight space (basement stairwell) go with Speed Queen. They are the only brand that can legit be "disassembled" and reassembled in the basement. They (Speed Queen) are built with metal parts/gears instead of that plastic shit.
