Most of them are. My dad is an appliance repair guy, he says the front load washer reliability problem isn't caused by the washer. They are often marketed as holding far more since there isn't an agitator, which is true, more fits in there. They also use less water for efficiency reasons. They ALSO spin faster which helps make the dryers work easier. The problem is, more water makes life easier on the washer, and makes for cleaner clothes with less crazy ringing. Less water, plus more crazy ringing, plus crazy fast spin dry, PLUS all of The extra weight the salesman told you would fit in there is a recipe for fried bearings, among other things. A bearing job on one of those is a nightmare, and they charge a premium for the parts. Don't stuff clothes in one, don't even fill it to the top. You can even turn off the high speed spin. How does this make them better than the old ones? Good question, but they sure are hella expensive, aren't they?
Also the all in one units blow big time. Don't bother, a stackable one is just like the side by side ones in different packaging.
For brands, stick with whirlpool owned companies including amana, maytag(for new ones, they only recently we're bought out) and a few others. Avoid GE, they suck, and when they break parts cost double. GE doesn't make their stuff, they buy from the cheapest Bidder and stick their name on it. Same for kenmore, Sears, and other box store brands. In the past they could be rebadged good ones, but lately it's more likely Chinese or Mexican stuff.
Avoid LG, they were caught programming their machines to know when they were being tested, and use less power to get fake numbers. It's a corrupt company. for a while they also wouldn't sell parts to people who wouldn't do warranty work for them, until they realized not paying well for that kind of work means nobody does it, customers get pissed, and buy something else.
Whirlpool products are usually good, and when they aren't at least they are designed for easy service and parts are priced fairly. They aren't as cheap, but long run you'll be better off.
