Don't know about the 1-16,however the 1-18 I had sudslocked quite often. The clutch had to be replaced twice. The third time the cluch went out,the machine went to the alley. Other than that problem, I loved the wash action of my 1971 1-18, and the fast spin. However, I did not like the control panel design. In fact, the only Frigidaire control panel designs that I do like are the 1957,1958,1959, and 1960 models. (now don't we all) LOL!! They are all fun to watch, but other than the 57-60 models, I do not want one. They are still very nice to see in someone else's collection.
The WP Sugilator in my 1956 WP turns over 7 pair of jeans very well. The 58 Maytag does not turn even 5 pair of them well at all. The 65 Kenmore does not turn jeans as well as the WP,but is better than the Maytag. The Super-Roto-Swirl also has another problem with large loads of jeans: When the tub is packed,the Roto-Swirl sometimes wraps the leg of the jeans around itself,thus stopping all turnover. So much for that load...
BTW: the 56 WP runs slightly faster than the 65 Kenmore. My 58 Maytag runs slower,but has longer strokes than any Maytag I have ever seen. I am rebuilding a 56 Kenmore right now. Am wondering if it will run the same speed as the 56 WP,or the 65 KM??
I would have to say there are many reasons why one person may dislike a certain brand,or another. I do love the KM/WP 1950's and 1960's models only. But if someone else does not,I really do not care. I cannot give an opinion on any modern appliances. Do not own any,and do not care to know about them. Never read the "blue" section here. I do have to say that any vintage appliance 30+ years old is a surviver,and should at least be respected for that, if nothing else. I will only own vintage GM cars. When I attend a car show, I try to check out all the vintage brands of cars. Not that I would ever own a Ford, or Chysler, but I still have a liking for those brands, and the people who restored and maintain them. Same goes with vintage appliances for me.
