Frigidaire had push-to-start knobs for some of their machines, as well as some other brands, so Kenmore wasn't the only one. However, I believe it was one of the last brands to make the transition to pull-to-start! Here's what I think of the Whirlpool/Kenmore problems...
1. The D-shaped lid opening doesn't get in the way of loading the clothes for me, but changing out AGITATORS! It was tough trying to get the winged Surgilator in and out of the Frankenmore and 24" Kenmore, but it fit both perfectly!
2. The water pump is easier to change than the belt. 'Nuff said.
3. Why can't the lid be used as a loading shelf, a la Frigidaire, Westinghouse, Norge, etc.? And over time the weight of the lid put strain on the stop, causing it to sag.
4. Slow 525 RPM spin, 505 for large capacity.
5. The outer tub is a horrible design; if the machine is not level, water WILL remain in it. Not only that, but it is absolutely poor for sediment draining, which means it's prone to buildup over time. On the old '68 Kenmore, I pulled sediment "flakes" out that were 1/8" thick!
6. Too many bearings to fail in the centerpost.
So if Whirlpool/Kenmore machines have a few inconveniences, are unnecessarily Rube Goldberg and a b*tch to work on, and aren't the best performance-wise, why is it we love them so much? I think it's not only because of their against-the-odds reliability, it's because they simply have a "following" and are what we are most familiar with seeing. For me, it's all the different types of agitators used as well as the sounds and the wash action. There's just something about them that makes them FUN TO USE AND WATCH!!!
Whirlpool's DD machines are good, reliable performers, IMHO, and their dryers are good as well!
Speaking of against-the-odds reliability, I think it was Greg that mentioned to me about how the Kenmore combos, with more parts than a Volkswagen, weren't as trouble-prone as one would think. Does anyone have any more information on this?
