I have the Maytag mvwp575gw and now the TC5.
Maytag 575 has been without issues now for four years used for a family with pets. It is probably the second best build residential top load that can be bought (although the GE Commercial may be similar). It is very similar to the TC5 in what most people see and can test from the outside with the exception of the suspension. It is a hung suspension. The plastic outer basket is attached by rods to the four corners of the machine. For that reason the tub does move around. I have not had any issues balancing loads when like items are washed. If you want to wash an odd-sized item, balance it with something of equal size and weight. It really is that simple. Included in the price is a five year in-home parts and labor warranty. Much cheaper, cleaner, and more convenient than going to a laundry mat.
Where the TC5 feels sturdier is the suspension. It has a metal outer tub attached. Heavy-duty springs attach the bottom of the tub to the base.
The other issue not so easy to see is the difference in the gear case versus a real transmission.
With either washer, it is likely that most retire the washer at the point the gear case/bearings (Maytag) or bearings (SQ TC5) go out. One thing to note is there are videos that show changing a gear case and transmission out. Changing a gear case out seems much simpler. And guess what? It looks like it's easier to do the bearings too because the gearcase/bearings seems to be one part on the Maytag. That is interesting. Although I probably will not replace this when mine goes out as I won't have a need for two washers then, I plan to keep this washer in storage in case I cannot repair the SQ later and ECO restrictions have gotten worse.
In some places, the SQ TC5 is selling for $500 or $600 more than the Maytag 575. Most who take care of the Maytag are likely to see about 8-10 years possibly with a few inexpensive and minor repairs. Most who take care of the SQ TC5 are likely to see about 12-15 years possibly with a belt replacement. These are the numbers I see when browsing consumer boards and not boards like this where people can get parts for costs and know how to repair major issues themselves.
While the Maytag may not last as long, there may be a significant difference in cost making the Maytag a more attractive option for the family that is on a limited budget that needs something to work now and in the near future. The Speed Queen TC5 does have some more options for smaller loads, and that is why it may work better for a single person, couple, or family that needs the small load option. It also should have less frequent repairs. Though they are minor in the Maytag, some may not be able to do the repairs themselves. In some areas, the TC5 is not available or you have to be put on a waiting list.
This is what is sold today. Posts saying the Maytag is
