But there's a HUGE difference in terms of ability to clean. If I'm out doing yardwork and I have a pair of jeans with deep mud stains on the knees the old style top loader agitators can clean them just fine. The front loaders cannot no matter how many times I run them through. I end up having to scrub the jeans between my knuckles in the laundry sink - moderate agitation breaks up the mud and it rinses out easily.
I suspect a lot of this "agitators are rough" nonsense comes from modern washers that don't use a sufficient amount of water. But the SQ has a setting to use the normal amount of water so it's a non-issue. Most analysis I've seen (eg: from Consumer Reports) refuses to consider top loaders with normal water usage settings -- the data is basically invalid. A lot of Consumer Reports analysis has this type of problem where the entire study is built on a false premise.
Front loaders might be fine if your clothes never get dirty and only need occasional light rinsing. They're really terrible for actually cleaning dirt.
