I think of many worse classic washers- most of the very first automatics, WCI Frigidaire, Franklin Frigidaire, the rollermatic, Montgomery Ward, Norge, Hotpoint, Blackstone, Apex ect. Even the Unitmatic as great as they were tangled sheets.
The filter flo not only out-cleaned many of these washers while solving their flaws, the latter filter flos also lasted being true workhorse machines.
If anything the filter flos are number 5th inline being next to the Whirlpool direct drive, Original Whirlpool belt drive, Maytag dependable and two belt Raytheons. Most every other washer like the Frigidaire Galleries, Maytag Performas, Atlantis, ect follow behind the filter flos in over all value.
If I had to choose between any model T and a single speed filter flo I hands down take the filter flo. It is gentler, cleans better, rinses better, easier to repair and above all lasts many years.
The funky smell you speak of is a person who is not using their washer correctly. Its funny, because when front load washers mold, smell or stink AW.org blames the user, but when a filter flo gets funky GE's design gets the blame.
