Tom:
The two that always stood out for me were Maytag's A906 and Kenmore's Lady Kenmore. Both were extremely high-quality appliances, but each took a different approach to luxury.
With the Lady Kenmore, there were many different cycle selection buttons, as well as cycle modification options you could select via the dial. There were also three motor speeds. What it gave you was nearly infinite flexibility; you could custom-tailor a cycle for almost any kind of load. Back when I had a 1966 Lady K, I washed antique table linens in it with great success. I also washed the bag to my mower's grass catcher, with equal success *. Now that's versatility.
With a 906, you had pushbuttons and nothing else; the cycles were what they were and could not be modified. This approach was better for the consumer who wanted to give laundry good care without having to put a lot of effort into considering what cycle or modifiers were best to use for a given load. You pushed one button, and then you walked away; there really wasn't a whole lot of interactivity with the machine.
Both were fairly complex, in different ways. The Lady K was more complex mechanically; the 906 was more complex electronically. The 906's mechanical architecture, held in common with every other top-loading machine in Maytag's line, was, in my opinion, more robust than the Lady K's. But Lady Ks were also very dependable machines.
If I had to choose one today, it would depend on circumstances. If I had pretty deep pockets, I would choose a 906, because if there is an electronic problem, it can take some luck and some money to get things back on track. If I didn't want to have to worry about such things, I'd choose the Lady K, though there would always be a bit of a worry about the dispenser assembly, which is NLA and frankly, pretty complicated.
So, the Lady K was for the consumer who wanted control over everything, the 906 was for the consumer who wanted the luxury of having the machine do everything without intervention.
* Washing a grass catcher bag will help it last much longer than it would otherwise; grass clippings are fairly acidic, and eat the fabric if not washed away. Soak, then gentle cycle, warm water, some extra detergent and no bleach or softener. Be sure and clean your lint filter afterwards, and wipe the tub, to remove any bits of grass. Once at mid-season and once before putting the mower away for the Winter is plenty.
